1) No its never good to give someone the cold shoulder
2) Add something interesting like a video or make a story (fictional would be good)
3) ..i think this is more of a personal question so you would have to choose this one
4) You could ask the person how there day is and ask them what they like to do to see if you have something in common
<span>C is the correct answer. There is an understood you as follows: “for once in your life, [you should] try something new and exciting”. ‘For once in your life’ in this sentence is an adjunct and is extra information given to emphasise the strength of the speaker’s feelings.</span>
The 'paragraph' is not a paragraph, because almost all the sentences are incomplete, choppy, or run-on.
hope this helps
