Question

Having a little trouble understanding the question.

Answer 1

I'm not good in english but i'll try to help

you have to identify the error in the sentence.
i don't think it's double comparison because it only use the word "longer" to compare, if it says "more longer" then this will be your answer.
For illogical comparison --> i think this one because the sentence is comparing the feet to a person
There is no double negative in the sentence.
The sentence also uses the correct degree of modifier "longer than" because it is comparing two people :)
hope this helps
