My younger brother used to detest fish , but now he like?
a. eats b. ate c. eating d. eat

Here the correct answer is C

because each is self-sufficient.  

for this, you need to remember something significant in your own life, for example, if you were bullied when you were younger, you can mention your memories on this and touch on how such treatment can harm other kids your age either physically or mentally. (racism, car crashes, a parent in the hospital are all very good subjects, think hard on it! )
