The Interrogative Sentence
A second sentence which may be classed with the preceding is the interrogative. There is a disposition on the part of speakers to ask direct questions of the audience. Frequently the rhetorical question—which is one asked because the answer is the quite apparent fact the speaker wants to impress upon his hearers—is an effective method of making a seemingly personal appeal to sluggish intellects or lazy wills.
The interrogative form has the same disadvantage as the exclamatory. Except when its answer is perfectly plain it transfers no meaning. It would be easily possible for a speaker with no ideas at all, no knowledge of a topic, to engage time and attention by merely constructing a series of questions. At the conclusion the audience would wonder why in the world he spoke, for he had so little to say.
