Question

Identify the sentence in which the underlined pronoun is used incorrectly. A Watch where you're going! B. Have yo turned in you're English paper? C. Do you remember you're giving me the key? D. Your bicycle was left outside in the rain overnight.

Answer 1

The answer is B. Remember "You're" stands for "You are"... so all you have to do is read the sentences and instead of saying you're, say you are. 

Answer 2

The answer is B: Have yo turned in you're English paper? The correct use of the pronouns are: Have you turned in your English paper?  -- you (personal pronome) and your (possessive pronoun). The personal pronouns substitute that represent people: I, we, they, she, he etc. The posseve pronouns show possession: their, his, her, our etc. The sound of you're (you are) is almost like the sound  of your.
