Here’s my two cents’ worth on the key errors from getting to what the sentence really means:
The stem means to say that doing well in school is akin to playing a game of marbles, and that doing well in school is being compared this way because such an achievement requires luck - according to a specific group of people (the not-your-average, harsher ones) among education cynics.
Now there are a few key problems, namely:
1. A metaphorical construct (success) is being compared to an activity (game of marbles) - on the GMAT, this is not considered a grammatically Apple-2-Apple comparison. We need to find something that compares either an activity or action to another activity or action.
2. The statement is made by a specific group of people, which are the ones who are more cynical than usual towards education.
3. We need to find proper comparative words eg when comparing nouns vs nouns, ‘like’ is preferred to other forms eg ‘as’.
Error analysis:
1. A is out since a metaphorical construct (success) is being compared to an action/activity of playing a game of marbles.
2. Change of meaning: the statement of comparison was made by a specific group of cynics, however in B it is suggesting some unspecified general group of people are making this comment.
3. Change of meaning: Succeeding in school is being compared to playing a game of marbles; however, in C, school is not just likened but in fact is being said to BE a game of marbles. C is out for this reason that the answer choice mistakenly says that when A is like B, A is B - this may not be foolproof and we should keep the level of ambiguity in the stem. On top of that, C is missing a conjunction; even if it didn’t, C would still be out for reasons cited above.
4. Succeeding is being compared to playing (one activity compared to another), while keeping the level of reference made by the specific group of cynics.
5. E commits the same error as in A, hence out.
