　　Answer to Question 1

　　Choice E is best.

　　The pronoun that in A and B should be deleted, since the pronoun one is sufficient to introduce the modifier and the sentence is more fluid without that.

　　In B and C, it and that it are intrusive and ungrammatical: the idiom is "believe x to be y." In the context of this sentence, the infinitive to be is more appropriate than the limited present-tense is in rerring to an event that occurred long ago but has been discovered only recently.

　　Finally, A, B, and D lack o/and so illogically equate this particular explosion with the whole class of explosions to which it belongs: it is not a type but possibly one of a type.

　　Answer to Question 2

　　A is the best choice.

　　Choices B, C, and D incorrectly omit that after agree; that is needed to create the parallel construction agree that there is waste . . . and that the government... spends.

　　Choice E, though it retains that, is grammatically incorrect: because E starts with an independent rather than a subordinate clause and separates its two independent clauses with a comma, it creates a run-on sentence with no logical connection established between the halves.

　　In B, the agreement ... to the fact is unidiomatic, and B, C, and E alter the sense of the original sentence by saying that voters agree rather than that they may agree.
