Facts
Question: How long did American Civil War last? A. 4 years and 1 month B. 3 years and 1 month C. 5 years and 1 month
### Reasoning: Step 1: Identify the event: The question is about the duration of the American Civil War. Step 2: Recall or retrieve information about the start and end dates of the American Civil War. Step 3: The American Civil War started on April 12, 1861, with the attack on Fort Sumter. Step 4: The American Civil War ended on April 9, 1865, with the surrender of Confederate General Robert E. Lee at Appomattox Court House. Step 5: Calculate the duration by subtracting the start year from the end year: 1865 - 1861 = 4 years. Step 6: Determine if there were any months between the start and end months. Both the start (April) and end (April) months are the same, indicating the duration is exactly 4 years. Step 7: Check for any specific month within the four-year span that might indicate a slight extension or reduction.

Facts
Question: How long did World War I last? A. 4 years, 3 months and 14 days B. 4 years, 5 months and 5 days C. 4 years, 3 months and 6 days
### Task: dur_compute ### Reasoning: Step 1: Identify the event: The question is asking about the duration of World War I. Step 2: Recall or look up the start and end dates of World War I. Step 3: World War I started on July 28, 1914, and ended on November 11, 1918. Step 4: Calculate the duration by subtracting the start year from the end year: 1918 - 1914 = 4 years. Step 5: Determine the month difference between the start and end months. The start month is July and the end month is November. Counting the months from July to November, we have July, August, September, October, November, which is 5 months. Step 6: Determine the day difference between the start and end days. The start day is 28th and the end day is 11th. To find the number of days, consider the days remaining in July after 28th (31 - 28 = 3 days) and add the days in August (31), September (30), October (31), and November (up to 11th). Days in August = 31, Days in September = 30, Days in October = 31, Days in November until Nov 11 = 11. Total days = 3 + 31 + 30 + 31 + 11 = 106 days. However, this is incorrect. Let's recalculate days from July 28th to Nov 11th directly. Step 7: Days in July after 28th = 31 - 28 = 3 days. Step 8: Days in August = 31 days. Step 9: Days in September = 30 days. Step 10: Days in October = 31 days. Step 11: Days in November until Nov 11 = 11 days. Step 12: Total days = Days in July (after 28th) + Days in August + Days in September + Days in October + Days in November = 3 + 31 + 30 + 31 + 11 = 106 days. This is still incorrect. Let's simplify by considering the full months in between. Step 13: From July 28, 1914 to July 1, 1915 is exactly 12 months (1 year). Step 14: From July 1, 1915 to November 11, 1918 is less than a year. Let's calculate it precisely. Days remaining in July 1915 = 31 - 1 = 30 days. Days in August 1915 = 31 days. Days in September 1915 = 30 days. Days in October 1915 = 31 days. Days in November 1915 = 30 days. Days in December 1915 = 31 days. Days in January 1916 = 31 days. Days in February 1916 = 28 days (1916 is not a leap year). Days in March 1916 = 31 days. Days in April 1916 = 30 days. Days in May 1916 = 31 days. Days in June 1916 = 30 days. Days in July 1916 = 31 days. Days in August 1916 = 31 days. Days in September 1916 = 30 days. Days in October 1916 = 31 days. Days in November 1916 = 30 days. Days in December 1916 = 31 days. Days in January 1917 = 31 days. Days in February 1917 = 28 days (1917 is not a leap year). Days in March 1917 = 31 days. Days in April 1917 = 30 days. Days in May 1917 = 31 days. Days in June 1917 = 30 days. Days in July 1917 = 31 days. Days in August 1917 = 31 days. Days in September 1917 = 30 days. Days in October 1917 = 31 days. Days in November 1917 = 30 days.

Question: How long did Vietnam War last? A. 19 years, 4 months, 4 weeks, and 1 day B. 19 years, 5 months, 4 weeks, and 1 day C. 19 years, 6 months, 4 weeks, and 1 day
### Reasoning: Step 1: Identify the start and end dates of the Vietnam War. Step 2: The Vietnam War started in 1955 (or 1959 depending on perspective) and ended in 1975. Step 3: Calculate the duration by subtracting the start year from the end year: 1975 - 1955 = 20 years. Step 4: Check for any significant month differences. The war began in September 1955 and ended in April 1975, indicating a slightly less than full year difference within the overall 20-year span. Step 5: Refine the duration by considering the exact months. From September 1955 to April 1975 is indeed very close to 20 years, but slightly less. The options suggest a more granular breakdown. Step 6: Examine the options. Option A suggests 19 years, 4 months, 4 weeks, and 1 day. This is the most precise breakdown and aligns with historical accounts that pinpoint the start and end dates. Step 7: Verify if there's a minor event within the war duration that could account for the extra days and weeks. The Tet Offensive in January 1968 is a significant event, but doesn't explain the entire duration. Step 8: Conclude that the most likely answer is the one that provides a detailed breakdown matching historical records closely. ### Final Answer: \boxed{A}

Facts
Question: How long did Chernobyl Disaster Immediate Aftermath last? A. 2 weeks B. 3 weeks C. 1 week
### Reasoning: Step 1: Identify the event: The question is about the 'Chernobyl Disaster Immediate Aftermath'. This refers to the period immediately following the Chernobyl Nuclear Power Plant disaster in 1986. Step 2: Recall the nature of the aftermath: The immediate aftermath would include initial response efforts to contain the accident, rescue operations, and initial evacuations and health assessments. Step 3: Retrieve or estimate the duration: The initial response to contain the disaster and stabilize the situation was extensive and ongoing. While there were initial days of emergency response, the full 'immediate aftermath' likely spanned several weeks as containment efforts continued and broader consequences became evident. Step 4: Compare with provided options: The options are very short durations (1 week or 3 weeks). Given the scale of the disaster and the need for coordinated international efforts, the immediate aftermath could not have been confined to just a few days. Step 5: Conclude and select the best answer: Based on general knowledge about major nuclear disasters and the scale of the Chernobyl incident, the immediate aftermath lasted longer than a week but less than a month. Option B (3 weeks) seems more reasonable than Option A (2 weeks) or Option C (1 week). ### Final Answer: \boxed{B}

Question: How long did Prohibition Era in the U.S. last? A. 13 years, 9 months and 19 days B. 13 years, 10 months and 19 days C. 13 years, 8 months and 19 days
### Task: dur_compute ### Reasoning: Step 1: Identify the start and end points of the Prohibition Era. Step 2: The Prohibition Era started with the ratification of the 18th Amendment on January 16, 1919. Step 3: It ended with the ratification of the 21st Amendment on December 5, 1933. Step 4: Calculate the duration from January 1919 to December 1933. Step 5: From January 1919 to December 1919 is exactly 1 year. Step 6: From January 1920 to December 1929 is 10 years (every year). Step 7: From January 1930 to December 1933 is 4 years. Step 8: Add up the durations: 1 year + 10 years + 4 years = 15 years. Step 9: Check the start date again. The start was *after* January 16, 1919, meaning it was sometime in 1919 after January 16th. So, it's less than 1 full year from Jan 16, 1919 to Jan 16, 1920. Step 10: Refine the calculation by considering the start date more precisely. The era began shortly after January 16, 1919. Let's assume it started right after the ratification, which is effectively the next day, January 17, 1919. Step 11: Calculate from January 17, 1919 to December 5, 1933. Step 12: Years between 1919 and 1933 inclusive: 1920, 1921, 1922, 1923, 1924, 1925, 1926, 1927, 1928, 1929, 1930, 1931, 1932, 1933 = 14 years. Step 13: Adjust for the starting day. From January 17, 1919 to January 16, 1920 is slightly less than a year. From January 17, 1919 to January 16, 1920 is exactly 364 days (12 months minus 1 day in 1919). Step 14: From January 16, 1920 to December 5, 1933 is calculated as follows: 11 months and 28 days in 1920, then 12 months each in 1921-1932 (12 years), and finally 11 months and 27 days in 1933 (from Jan 16 to Dec 5). Step 15: Total months = 11 (Jan-Feb 1919) + 12 * 12 (1920-1933) + 11 (Dec 1933) = 156 months. Step 16: Total days = 364 (Jan-Feb 1919) + 365 * 12 (1920-1933) + 27 (Dec 1933) = 4379 days. Step 17: Convert days to years: 4379 days / 365 days/year = 12.0027 years. Step 18: Refine further. From Jan 16, 1919 to Jan 16, 1920 is exactly 1 year. From Jan 16, 1920 to Dec 5, 1933 is calculated as follows: 11 months + 28 days in 1920 = 116 days. Then 12 months each in 1921-1932 = 12 * 365 = 4380 days. And 11 months + 27 days in 1933 = 360 days. Total = 116 + 4380 + 360 = 4856 days. Step 19: 4856 days / 365 days/year = 13.293 years. Step 20: Consider the month difference.

Facts
Question: How long did The Great Depression last? A. 10 years B. 5 years C. 20 years
### Reasoning: Step 1: Identify the start and end points of The Great Depression. Step 2: Determine the start year based on historical knowledge. The Great Depression started in 1929 with the stock market crash. Step 3: Determine the end year based on historical knowledge. The Great Depression officially ended in the United States when the economy recovered enough to be considered out of depression, which was around 1941-1942. Step 4: Calculate the duration by subtracting the start year from the end year: 1941 - 1929 = 12 years (or 1942 - 1929 = 13 years if considering until the full recovery kick-in). Taking the beginning of the recovery as the end point is more appropriate for defining 'how long it lasted'. Step 5: Find the closest answer choice to the calculated duration. The calculated duration is approximately 12-13 years, but closest to 10 years among the given options. ### Final Answer: \boxed{A}

B
Facts
Question: How long did Gulf War last? A. 5 months, 3 weeks and 5 days B. 6 months, 3 weeks and 5 days C. 7 months, 3 weeks and 5 days
### Task: dur_compute ### Reasoning: Step 1: Identify the event: The question is about the duration of the Gulf War. Step 2: Retrieve information about the Gulf War's duration. Recall or search for historical knowledge about the Gulf War's start and end dates. Step 3: Determine the start date of the Gulf War. The Gulf War began on January 17, 1991. Step 4: Determine the end date of the Gulf War. The Gulf War concluded on February 28, 1991. Step 5: Calculate the duration in months by considering the number of full months between January and February. There is exactly 1 month between January and February. Step 6: Calculate the duration in weeks. Since the start and end dates are within the same month and close to each other, there are approximately 4 weeks between them (from the 17th of one month to the 28th of the next month). Step 7: Calculate the duration in days. The number of days between January 17, 1991 and February 28, 1991 can be calculated. January has 31 days. Days from January 17 to January 31 = 31 - 17 = 14 days. Days in February until Feb 28 = 28 days. Total days = 14 + 28 = 42 days. Step 8: Combine the calculated months, weeks, and days to express the duration in the required format. Step 9: Compare the calculated duration with the given options. Option C states 7 months, 3 weeks and 5 days, which is incorrect based on the calculation. Step 10: Re-evaluate the number of weeks. If we consider 'weeks' as a rough approximation, and knowing that 4 weeks is slightly less than the actual duration, we might need to adjust. Let's consider the duration as roughly 5-6 months. Step 11: Based on common historical knowledge and approximations, the Gulf War is often described as lasting around 5 months. Option A (5 months, 3 weeks and 5 days) seems to be the closest match to a commonly stated duration. Step 12: Final Answer: Select the option that best matches the calculated or commonly known duration. ### Final Answer: \boxed{A}

We need to consider the months as well. If we count full years, from July 2003 to July 2018 is 15 years. However, from July 7, 2003 to June 10, 2018, it is slightly less than 15 years but still very close. Step 7: Alternatively, calculate year by year. 2003-2004 (1 year), 2004-2005 (1 year), ..., 2017-2018 (1 year). That's 15 years. But since it ended in June, it's slightly less than 15 years. Let's be precise and check if it's closer to 15 or 16. If we consider full years from July 2003 to June 2018, it is indeed 15 years. Step 8: Based on the calculation and understanding of the timeframe, the duration is 15 years. Step 9: Match the calculated duration with the given options. Option A is 15 years. Step 10: Final Answer is based on the calculated duration and matching with the options. ### Final Answer: \boxed{A}

### Task: dur_compute ### Reasoning: Step 1: Identify the given information. The question asks for the duration of the Korean War. Step 2: Retrieve or recall the known duration of the Korean War. The Korean War is a well-documented historical event that lasted from June 25, 1950, to July 27, 1953. Step 3: Calculate the duration by subtracting the start date from the end date. Step 4: Start from June 25, 1950. Count forward month by month. Step 5: From June 25, 1950 to July 25, 1950 is 1 month. Step 6: From July 25, 1950 to July 25, 1951 is 1 year. Step 7: From July 25, 1951 to July 25, 1952 is another year. Step 8: From July 25, 1952 to July 25, 1953 is another year. Step 9: In total, the war lasted for 3 years. Step 10: Check the options provided. Option B states 4 years, 1 month and 2 days, which is incorrect. Step 11: Option C states 3 years, 1 month and 2 days, which is also incorrect. Step 12: Option A states 3 years, 2 months and 2 days. This is close, but not entirely accurate based on our calculation. Step 13: Re-evaluate the calculation. The war ended on July 27, 1953. Let's consider the duration from June 25, 1950 to July 25, 1950 being exactly 1 month. Step 14: Then from July 25, 1950 to July 25, 1951 is 1 year. Step 15: From July 25, 1951 to July 25, 1952 is another year. Step 16: From July 25, 1952 to July 25, 1953 is another year. Step 17: So, 3 years. Step 18: Now consider the days. From July 25, 1953 to July 27, 1953 is 2 days. Step 19: And from July 25, 1950 to July 25, 1953 is 3 years, which is 36 months. From July 25, 1953 to July 26, 1953 is 1 day. So from July 25, 1950 to July 26, 1953 is 36-1 = 35 months. But we need from July 25, 1950 to July 27, 1953, so it is 35 + 1 = 36 months - 30 days (from July 25 to July 25 next year) = 36 - 30 = 6 months. No, this is wrong. Step 20: Let's count months again carefully. From June 25, 1950 to July 25, 1950 is 1 month. Step 21: From July 25, 1950 to July 25, 1951 is 1 year. Step 22: From July 25, 1951 to July 25, 1952 is another year. Step 23: From July 25, 1952 to July 25, 1953 is another year. Step 24: So, 3 years. Step 25: Days from July 25, 1950 to July 25, 1953 is 3 years * 365 days/year = 1095 days. Days from July 25, 1950 to July 26, 1953 is 1096 days. Days from July 25, 1950 to July 27, 1953 is 1097 days. No, this is wrong. Step 26: Let's calculate months again from June 25, 1950 to July 25, 1950 is 1 month.
