The wrong sentence is: 3. 

I have never travelled by air. What it like flying in the sky? 

Here's why: Sentences 1, 2, 4, and 5 are grammatically correct and convey their meaning clearly. Sentence 3 has an error in subject-verb agreement. "What" is singular, but it needs a verb form that agrees with the plural subject "I have." Here's the corrected version: I have never traveled by air. What is it like flying in the sky? (We use "is" because "what" refers to the general concept of "flying in the sky") pen_spark tune share more_vert
