B) classes that allow teachers to advance to the next grade level along with their pupils and give

B v/s E but i'd choose E.

Here's why :

A) classes; that allows teachers to advance to the next grade level along with their pupils, to give.
"that allows" doesn't go with "looping classes". Also, "to advance.....to give" - should've been "to advance....AND to give" .

B) classes that allow teachers to advance to the next grade level along with their pupils and give
"that allow teachers TO advance....and TO(missing) give" . Parallelism!

C) classes and allow teachers to advance to the next grade level along with their pupils and give
1) classes AND allow teachers is incorrect. should be "classes THAT allow teachers" .

D) classes, which allows teachers to advance to the next grade level along with their pupils, giving
looping classes ..allows - Subject Verb Disagreement

E) classes, which allow teachers to advance to the next grade level along with their pupils, giving
best of the lot.

What's the OA?

A) classes; that allows teachers to advance to the next grade level along with their pupils, to give

looping classes is plural and the phrase modifying it cannot be singular , which mean "that allows " is wrong


B) classes that allow teachers to advance to the next grade level along with their pupils and give
This statement is perfect , subject-verb agreement and parallelism is perefectly put here . HENCE RIGHT ANSWER


C) classes and allow teachers to advance to the next grade level along with their pupils and give

allow teachers phrase is supposed to modify the action of looping classes , which means it is dependent on the first phrase of looping classes, And will make it equal which is wrong here.


D) classes, which allows teachers to advance to the next grade level along with their pupils, giving

Missing parallelism , as all sentences seem to be in simple present which gets spoiled by "giving" in the end and Allows is singular and not acceptable


E) classes, which allow teachers to advance to the next grade level along with their pupils, giving
same as above , missing Paralellism .

1. An increasing number of schools are experimenting with looping classes that allow teachers to advance to the next grade level along with their pupils and give

I'm not very good with the rules of grammar but i THINK the reason "why classes are allowing the experiment and not experimenting" is that 1. classes is the noun that is the closest to the fact explained "that allow teachers to.. " 2) Also, if experiment had to be linked to "that allow teachers...", the sentence would've said "an inc. no. of schools are performing experiments that allow teachers..." NOT "are experimenting that allow teachers..."

Again, pls pardon my bad sense of rules but this is the best reasoning i could come up with :oops:

Does anyone know why B is ok in terms of parallelism ?
classes that allow teachers TO advance to the next grade level along with their pupils and (TO?? ) give ?

Thanks !

Parallelism is pretty concrete in Sentence Correction, but there is an area where the GMAT gets relaxed. The preposition "to" can be omitted from the second element in parallelism because it's "understood". I like to eat hamburgers and (to) drink milkshakes. That sentence is perfectly fine with or without the "to".

Your grammar rules are correct. The placement of the modifier next to classes means that we are modifying classes. The additional question is meaning-based - does it make sense for a class, a thing, to allow a teacher, a person, to do something? In this case it certainly does. Normally teachers are assigned to a grade level and they are with students for a year before the students move on. The new "looping classes" keep the teachers with the students so the new class type "allows" the teachers to stay with the students. Here is a different example: "The new bridge allowed the people across the river to get to town in half the time." In this example a thing is allowing people to do something they couldn't do before.

Thanks Kylie for the detailed explanation. I was very confused between B and E and somehow neither looked perfect to me . Why can't "giving" in E modify the whole "which allow...." expression? I believe "which" modifying "classes" in E should be okay and the reason we're not choosing E is the word "giving" . Right ?

Thanks !

This is a really good question. You are correct, we aren't choosing E because "giving" does not refer back to the "which" modifier. The problem is in trying to stack the -ing modifier after a non-essential modifier. The non-essential clause can be "omitted" from the sentence from a meaning standpoint. Watch what happens when we remove the non-essential clause: "An increasing number of schools are experimenting with looping classes, giving students the opportunity to form long-term relationships with their instructors." You can see here that the clause "giving students.. " doesn't make sense in the sentence without that non-essential modifier. Why does a looping class give this opportunity? We don't know because we don't really know what a looping class is.
