Identify each sentence as declarative, imperative, interrogative or exclamatory. Add the proper punctuation.

2. Imagine the traffic problems we'd have without it. I added a period and called this declarative. Is this correct?

Is sentence 2 imperative?
Yes.
Yes.
Both verbs in 1 and 2 ("Try" and "Imagine") have no stated subjects and are giving a command.
1. "Try to name another American inventor." - This sentence is imperative because it gives a command or makes a request. Your addition of a period is correct.
2. "Imagine the traffic problems we'd have without it." - This sentence is declarative because it makes a statement or expresses a fact. However, your addition of a period is not correct. In this case, the sentence should end with a question mark since it expresses a hypothetical question. The correct punctuation would be: "Imagine the traffic problems we'd have without it?"
