Question 3

The sentence "Measure the plywood twice to make sure your marks are correct" gives a command or instruction, which is an imperative sentence. Imperative sentences can end with a period. So the correct option is B.

The sentence "Now, that’s what I call a rollercoaster ride" is making a statement (declarative) or could also be seen as exclamatory in tone, but since it's stating an opinion about the rollercoaster ride, as a declarative sentence it should end with a period. So the correct option is A.

Answer:

B. imperative—add period
