Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_1696 ( "Year" real, "Total" text, "Less than a year" real, "One year" real, "Two years" real, "Three years" real, "Four years" real, "5\u20139 years" real, "10\u201314 years" real, "15\u201319 years" real, "20\u201324 years" real, "25 and more" real, "Unknown" real )

### Question ###
If unknown is larger than 1.0, what is the maximum two year amount?

### Accurate SQL ###

SELECT MAX("Two years") FROM table_1696 WHERE "Unknown" > '1.0'
