Your answers???

2. d
3. c
1 is right
2 is wrong.
3 is right
1. The correct answer is c) world-famous mathematician, as there should be no comma after "famous" because the adjective phrase "world-famous" should be hyphenated as one unit to modify the noun "mathematician."
2. The correct answer is d) no error, as there is no need for a comma before "and won." The sentence structure is fine without it.
3. The correct answer is c) Princeton, NJ, as there should be a comma after "Princeton" to separate the city name from the state abbreviation.
