The answers for simple questions in English are "Yes,"
"No," or "I don't know" (or its equivalent). The answers
for information questions are varied--because they are
used to ask about specific kinds of information.
Information questions are also called "Wh-" questions
because many of the words that are used to ask this
type of question begin with Wh-.

The difference in meaning is clear, however, because the grammar for subject and object questions is different (to be treated later). |
