It was __ hot to go out in the middle of the day.

• A. Too
• B. Very
• C. So
• D. Extremely

Answer: (A)

The meaning rests on the structure too + adjective + to + verb. Here, too hot means the heat was more than what’s acceptable for going outside, so going out isn’t possible. That pattern is used to show a degree that prevents an action. Other options don’t fit because they don’t express that impossibility with the same construction: very or extremely describe how strong the heat is but don’t convey that going out is impossible; and so would need a result clause like so hot that I couldn’t go out.
