This one is one of my all-time favorites, partly because sloths are kind of awesome. Plus, it’s a good illustration of something we discussed in this YouTube video (which, sadly, does not contain any sloths): if you don’t notice the tasty stuff in the non-underlined portions of the sentence, you might waste a ton of time on this question.

With that in mind...

Quote:
(A) sloths hang from trees by long rubbery limbs and sleep fifteen hours a day, moving infrequently enough

This sounds great. But it’s wrong.

Hopefully, you noticed the word “its” at the end of the sentence. That means that “sloth” needs to be singular. So (A) is spectacularly wrong because of the non-underlined pronouns buried at the end of the sentence.

Quote:
(B) sloths hang from trees by long rubbery limbs, they sleep fifteen hours a day, and with such infrequent movements

(B) has exactly the same error as (A): “its toes” and “its coat” need to refer to a singular sloth, and (B) only gives us the plural “sloths.”

The parallelism is also pretty wackball in (B). (And no, “wackball” isn’t a word. But it should be.) We have: “…sloths hang from trees by long rubbery limbs, they sleep fifteen hours a day, and with such infrequent movements…” So we have a verb (“hang”), a noun with a verb (“they sleep"), and a weird prepositional phrase (“with such infrequent movements…”). That’s very much not parallel.

So (B) is out.

Quote:
(C) sloths use their long rubbery limbs to hang from trees, sleep fifteen hours a day, and move so infrequently

The parallelism is defensible in (C). Sloths use their limbs to do three things: “hang from trees”, “sleep 15 hours a day” (I'm totally jealous!!), and “move so infrequently…”. Not bad.

Trouble is, “its coat” and “its toes” still require a singular referent, and “sloths” is plural in (C). So (C) can be eliminated.

Let’s compare our last two options side-by-side:
Quote:
(D) the sloth hangs from trees by its long rubbery limbs, sleeping fifteen hours a day and moving so infrequently
(E) the sloth hangs from trees by its long rubbery limbs, sleeps fifteen hours a day, and it moves infrequently enough

“Sloth” is singular in both, so the pronouns are cool now. That’s nice.

So then the only real difference is the parallelism. In (E), we have “the sloth hangs from trees…, sleeps 15 hours a day, and it moves…” Nope, that’s wrong: we have a verb, a verb, and then a noun and a verb. That’s not parallel.

But what about (D)? People like to tell me that it’s not parallel, either. But (D) is structured differently than (E): it’s a nice clause (“the sloth hangs from trees…”), followed by two parallel “-ing” modifiers (“sleeping” and “moving”). That’s great: “sleeping 15 hours a day” and “moving infrequently” both make perfect sense as modifiers for “the sloth hangs from trees”, since both of those “-ing” words tell us more about what happens when the sloth hangs from trees.

So (D) might not SOUND parallel, but it is. And it’s the best answer.

D correct , also sleeping || moving

Found throughout Central and South America, sloths hang from trees by long rubbery limbs and sleep fifteen hours a day, moving infrequently enough that two species of algae grow on its coat and between its toes.

(A) sloths hang from trees by long rubbery limbs and sleep fifteen hours a day, moving infrequently enough

sloths is not agreeing in number with its

(B) sloths hang from trees by long rubbery limbs, they sleep fifteen hours a day, and with such infrequent movements

sloths is not agreeing in number with its

(C) sloths use their long rubbery limbs to hang from trees, sleep fifteen hours a day, and move so infrequently

sloths is not agreeing in number with its

(D) the sloth hangs from trees by its long rubbery limbs, sleeping fifteen hours a day and moving so infrequently

sleeping fifteen hours a day and moving so infrequently maintains parallelism with Found throughout Central and South America

(E) the sloth hangs from trees by its long rubbery limbs, sleeps fifteen hours a day, and it moves infrequently enough

it moves infrequently enough is not parallel to the sloth hangs from trees by its long rubbery limbs

GMATNinja , I get why E is wrong. Now suppose we modify E to remove "it" after ",and". Which among D and E would be better ? Pl excuse me for this hypothetical question , but I often analyze different cases when I study. It helps me gain clarity !

Thanks in advance :)

"comma and" would make the sentence look like a list of 3 items { "the sloth hangs from trees by its long rubbery limbs", "sleeps fifteen hours a day", and "moves infrequently enough"} and these 3 items in sync causes "that two species of algae grow on its coat and between its toes". However per the intended meaning of sentence it is "infrequent movement" that cause "algae to grow"

Just tried answering it(I know it is asked from GMATNinja)

Mark two splits: sloths vs. the sloth (plural/singular) and ,moving vs. and move/moving (parallelism/modifier)

We can tell that towards the sentence, "its" marks that the subject is a singular noun

Also notice the "so ... that" construction

I am a bit curious about the "it's" used in D & E. Doesn't it sound ambiguous as it could refer to either the sloth or the trees and on that fact alone the two options in question can be negated?

Thanks for the response. Does the "that" part qualify the list or just the last element of the list ?

Supposedly you are asking 1. whether "that" is included in the list? 2. does "that" marks the end of the following list? (Pls let me know if I have accounted correctly)

To: 1. No, here particularly "that" is not part of the list
2. Here, "that" shows the beginning of a dependent clause and is providing additional information about the list of the independent clause

Hope this helps, if yes, let me know it by kudos :-)

Hi abhigulia3006, its can only refer to something singular and so, trees cannot be an antecedent of its.
