Fill in the blank with an appropriate option.
One of his rules was to always ________and await instruction to enter.
Answer & explanation
Correct answer: option 1
The correct option to fill in the blank is knock.
The sentence is about a rule that a person follows, which is to always knock on a door and wait for permission to enter. The word "knock" means to strike a door or other surface with the knuckles of a closed fist, typically to attract attention or gain entry.
The other options are not as appropriate:
- Rub means to move one's hand over a surface with a repeated back-and-forth motion. It would not be accurate to use "rub" in this context, as the person is not rubbing the door.
- Blink means to close and open the eyelids quickly. It would not be accurate to use "blink" in this context, as the person is not blinking at the door.
- Resist means to oppose or try to prevent something. It would not be accurate to use "resist" in this context, as the person is not resisting the door.
