#### OG13 SC Starfish, with anywhere from five to eight arms, hav

Tue Aug 23, 2016 6:18 pm
Starfish, with anywhere from five to eight arms, have a strong regenerative ability, and if one arm is lost it quickly replaces it, sometimes by the animal overcompensating and growing an extra one or two.

A one arm is lost it quickly replaces it, sometimes by the animal overcompensating and
B one arm is lost it is quickly replaced, with the animal sometimes overcompensating and
C they lose one arm they quickly replace it, sometimes by the animal overcompensating,
D they lose one arm they are quickly replaced, with the animal sometimes overcompensating,
E they lose one arm it is quickly replaced, sometimes with the animal overcompensating,

OA: B

Hi GMATGuruNY,

Can you please explain the logical connection between "with the animal sometimes overcompensating and growing" and the rest of the sentence? What does this modifier modify to?

Thx for your time in advance,
Victoria
Generally, a COMMA + with modifier that follows a clause serves to modify the preceding action.
OA: It is quickly replaced, with the animal sometimes overcompensating and growing an extra one or two.
Here, the action is blue (the arm is quickly replaced) happens WITH the event in green (the animal sometimes overcompensating and growing an extra one or two).
In other words, when the starfish replaces the arm, it sometimes overcompensates and grows one or two extra arms (in addition to the one being replaced).
Thx, GMATGuruNY. It makes sense that "with the animal sometimes overcompensating and growing an extra one or two" modifies " being quickly replaced".

The reason that "the animal" is placed between the proposition "with" and the present participle "overcompensating and growing" is that the subject of " it is quickly replaced" is "it ", referring one arm. Since "being quickly replaced" and "overcompensating and growing" are performed by two different agents, " the animal" is required to clarify the meaning of the propositional phrase, right?

WIth the same logic, can I say that the "the animal" in option C, " they lose one arm they quickly replace it, sometimes by the animal overcompensating", is redundant? Since "they" and "the animal" are both referring to starfish, it is not necessary to repeat it twice.

If the main clause is active (option C), there is no need to lead the action "overcompensating and growing " with "the animal" in the propositional phrase. On the other hand, if the main clause is passive (option B), then a subject referring to "the starfish" would be required to complete the meaning in the propositional pharse.

Thx for your time.

These lines of reasoning seem valid.

A one arm is lost it quickly replaces it, sometimes by the animal overcompensating and
B one arm is lost it is quickly replaced, with the animal sometimes overcompensating and
C they lose one arm they quickly replace it, sometimes by the animal overcompensating,
D they lose one arm they are quickly replaced, with the animal sometimes overcompensating,
E they lose one arm it is quickly replaced, sometimes with the animal overcompensating,
In A, the first it (singular) does not agree with its intended antecedent, starfish (plural). Eliminate A.

In D, the second they (plural) does not agree with its intended antecedent, arm (singular). Eliminate D.

In C and E, sometimes by the animal and sometimes with the animal imply a nonsensical meaning: that the lost arm is replaced sometimes NOT BY the animal or sometimes WITHOUT the animal.
Eliminate C and E.

The correct answer is B.

Where a modifier is placed affects MEANING.
Always notice when a modifier such as SOMETIMES changes position in the answer choices.
In the OA, sometimes correctly modifies overcompensating and growing:
If one arm is lost it is quickly replaced, with the animal SOMETIMES OVERCOMPENSATING AND GROWING an extra one or two.

Thanks, Mr. Hunt,

I have a specific question here -
If X, then Y

Here X and Y needs to be in the same voice; I mean active - active or passive-passive.

One author is saying so. Click Here.

The OE in the OG13 states the following:
In a conditional sentence if X, (then) Y, rhetorical flow is enhanced by the two clauses sharing the same structure. If one clause is passive, the other should be passive; if one clause is active, the other should be active, too.
