Question

Is the question of comparison wrong "" the weather this summer is worse than last year"" because I think the right must be"" the weather this summer is worse than the weather last summer""

Answer 1

both are correct.

the meaning of first and second statements are both same.in the first statement, they havent used the words "worse than the weather last summer" that is used in second statement. instead, they used simply" worse than last year,"that literally means the same as second statement's last words,"worse than the weather last summer".
