Read the paragraph.

once, tyrone had been a great marathon runner. the trophies sat on a shelf in his bedroom. that was long ago, before all the problems with his legs began. he could walk, but only slowly and with care. still, he would not give up. he now spent his days in his house, from room to room.

which verb best completes the sentence?

moving
shuffling
crawling
slinking

Shuffling

Explanation:

To better understand why "shuffling" is the best option, here is a brief explanation of why the other options are not correct:

"To move" means to go or pass from one place or position to another, although this may fit well into the blank space, this is not specific enough as the other options.

"To crawl" means to creep or to move slowly on our hands and knees. We can discard this verb because the sentence mentions that although Tyrone had problems with his legs, he could still walk.

"To slink" is also out of context because this verb means to sneak about furtively, or move smoothly and quietly with gliding steps, in a stealthy or sensuous manner, and the text does not make any reference of Tyrone being this way.

So, "shuffling" is the verb that best completes the sentence because "to shuffle" is to walk by dragging one's feet along. Tyrone has problems with his legs, but he can still walk, slowly, and with care, thus he could shuffle from room to room, as this is what his legs allow him to do, nothing more and nothing less.

B). Shuffling.

Explanation:

As per the question, the verb that completes and accomplishes the meaning of the sentence is 'shuffling'. The verb 'to shuffle' implies the meaning 'dragging or heaving one's foot' and since Tyrone's legs are not working properly(reflected by 'long ago...problems with his legs'), so, he could only be able to 'shuffle' gently from one room to another. The other options either exemplify out of context meanings(like 'slinking' in option D) or inappropriate(like 'crawling' in option C as Tyrone was able to walk slowly) or less appropriate to correspond to the meaning of the sentence. Thus, option B is the correct answer.

answer: c.   like someone who knows how to behave in public
