### English: Now let me tell you the reason why cans are expensive and where are they expensive?
### Errors: There is a major error of incorrect translation has stylistic problems at "and where are they expensive?". There is a minor error of incorrect translation includes information not present in the correct translation at "cans instead of canned goods".
