" Just as the image of the leper, cut off from all contact" . This is a Metaphor. A example of sin. The leper was isolated from everyone around him.
On the one hand, a <u>gerund</u> is a verb that acts as a noun, know for the -ing form. On the other hand, an <u>infinitive</u> is the basic form of a verb, that usually follows "to" or another verb form. The revised sentence, including both of these, is:
"To give is one of the best things people can do. Volunteering their time shows what caring people they are."
This passage reads like a script for stage or film.
The medium that would best interpret this passage would be film.
1) Camera focus in on Mrs Peters' eyes slowly turn to meet Mrs Hale's eyes.
2) Mrs Hales' eyes moving to spot the hidden box.
3) Sound of a knob turning with camera showing closeup of knob turning
Panning in & out on eyes and knob is best achieved through use of a camera in film.
The correct answer is A.
B is incorrect because instead of "more expensive than," it says "most expensive than," which doesn't make any sense.
C is incorrect because it implies the car is more expensive in this showroom than anywhere else it could be, which with the context of the answers, is completely irrelevant.
D is incorrect because it either serves as a fragment of a sentence which is incorrect, or fails by saying "in this showroom" instead of making a comparison, "than this showroom."
Therefore, A is the only sentence with proper grammar that makes sense. :)
