МатематикаВопрос:
3. I don't know what ______. a) do b) to do c) that I do
Ответ:
Краткое пояснение:
После вопросительных слов (what, where, when, how, who, why) в придаточных предложениях или косвенных вопросах часто используется инфинитив с частицей 'to'.
Пошаговое решение:
- Конструкция 'I don't know what' подразумевает косвенный вопрос.
- После 'what' в данном случае требуется инфинитив с частицей 'to'.
- Вариант 'b' - 'to do' - является правильным инфинитивом.
- Варианты 'a' ('do' - базовая форма глагола) и 'c' ('that I do' - полная клауза, не подходящая для косвенного вопроса после 'what') не соответствуют грамматике.
Ответ: to do
