Read the following passage: why didn't i keep my big mouth shut? sure what i said was true: no one could stand elliot's violin playing. but he had been so enthusiastic about it and after that, we never heard him play much anymore. now that he was gone, we'd all give anything to hear that wretched screeching again. you never know what it might end up costing you to be right. what is most likely the purpose of the passage? a. to teach that some things are best left unsaid b. to illustrate that you never know when life will change c. to point out that you never know how someone will interpret your words d. to show that even painful memories are precious

your eyes are the first things that you open

the correct answer is option d. none of these. it is noted that options a, b, and c share the same content.

despite the valid answer provided at the last sentence of each of the options, a question/answer format shouldn't include humourous themed responses such as "you bet your thermal pj's we do." - unless of course, the answer is carried out in an informal environment. this could be replaced with a simple "yes" or "it is necessary".

the question should be re-phrased to a more appropiate syntaxis. instead of "do we need the greenhouse effect? ", it should be written as "is the greenhouse effect necessary? " in order to give it a general scope, instead of limiting the answer to the needs of "we" the humans.
