My brother once built a tool shed entirely out of flattened tomato cans. it stood for two summers. when he was just ten years old, he created a kind of rudimentary moped out of an old bicycle, a lawnmower engine, and gasoline pilfered from my father's vw. it ran, about twenty yards down the sidewalk, but burst into flames before it reached the corner and nearly killed us. his were always the best halloween costumes in the county--a robot that oozed black goo one year and a talking refrigerator the next. he won awards at every school science fair but destroyed a lot of my family's belongings in the process.

now you need a topic sentence for the paragraph. which of the following would work best?
question 7 options:

a) my brother was a gifted inventor, but a dangerous one.

b) my brother was a danger to himself and others.

c) my brother was an interesting kid.

d) my brother was the most brilliant child i've ever known.
