Throught Process for #124 OG 12 Fri Apr 27, 2012 4:13 pm
Elapsed Time: 00:00
• Lap #[LAPCOUNT] ([LAPTIME])
Found throughout Central and South America, sloths hang from trees by long rubbery limbs and sleep 15 hours a day, moving infrequently enough that two species of algae grow on its coat and between its toes.

d. the sloth hangs from trees by its long rubbery limbs, sleeping 15 hours a day and moving so infrequently
e the sloth hangs from trees by its long rubbery limbs, sleeps 15 hours a day, and it moves infrequently enough

I only listed D and E because A, B, and C were obviously wrong due to subject/verb agreement. But I am confused as to why D is correct. It reads as if it is trying to say that while the sloth hangs from trees by its long rubbery limbs, it is sleeping and moving infrequently. is that right? i suppose that it could be correct.

I was looking for the answer that read "sleeps 15 hours a day, and moves infrequently enough"

E was closest to the parallelism so i chose that, but i understand the addition of "it" makes it not parallel after reviewing.

This was a really tough quesiton for me. I get it worng everytime, but is there anything else wrong with E? or what's so right about D? the sloth hangs...and verb+ing. why does it work in this case?

D uses a participial phrase ("moving...") to modify the subject ("the sloth")

E ruins the parallelism by using the pronoun "it".

In answer E "It" is incorrecyly used.

Instead E should be written as.
"sleeps 15 hours a day, and moves"

doesn't the moving and the sleeping modify the sloth, while he is hanging? is that supposed to be the intended meaning?

I did not understand the "subject verb agreement" problem in option A.
"sloths" is the subject - Plural
"hang" and "sleep" both are plural verb.

As per me subject-verb agreement is there in option A

Pls correct me if i m wrong.

@krishna
in non-underlined section it is mentioned that
Quote:
that two species of algae grow on its coat and between its toes.
"its" in this non-underlined part require that subject to singular

Can someone please explain why the "parallelism" in option C (see below) is wrong? Please for now ignore the sub-verb disagreement.

Found throughout Central and South America, sloths use their long rubbery limbs to hang from trees, sleep 15 hours a day, and move so infrequently that two species of algae grow on its coat and between its toes.

Thanks!
