In conditional sentences, isn't the comma necessary? .


Since the OA does not include a comma, the answer is clear: a comma is NOT necessary.

Please note:
The GMAT is not a test of punctuation.
An answer choice should not be eliminated solely because of the inclusion or omission of a comma.
One exception is an error known as a COMMA SPLICE:
If a comma can be replaced by a period -- implying that the comma is incorrectly serving to connect two independent clauses -- the answer choice is wrong.
Otherwise, do not discard an answer choice for a comma-related reason.

I fail this question

"overcompensating" and " growing" are not independent actions and the use of "and" is not suitable. A and B are out
the 2 actions are of the same event. comma+doing is used not "and"

I am confused. pls, help


same I crossed B because I thought growing had to modify overcompensate otherwise it does not make sense to have the verb "overcompensate" alone like that. Can somebody explain? And also would it be possible to explain what is exactly is wrong with E? Thx !


Let's Focus on B and E
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.


B one arm is lost it is quickly replaced, with the animal sometimes overcompensating and
E they lose one arm it is quickly replaced, sometimes with the animal overcompensating,

1 Usage of sometimes : meaning in E is changed, as if sometimes with the animal
Sometimes should come near what it is modifying...they replace it that results something

2. and should separate two different v-ing modifiers...
when we say IC1 , and IC2 then only it means IC1 and IC2 are independent
but when there is a list with common subject we can simply write sub X and Y
when there is a list with 3 or more in the list we need comma + and => x,y, and Z else X and Y



Thank you for proper explanation, I have one question about 2 different modifires.
in case of "overcompensating and growing" it is clear, but I have faced one question where two ajectives modifing the moun should be saparated by "comma" "," because they modify noun equally. ex: separate, required course.
so I am little confused when we can use "comma" and when "and" between modifiers?

In D and E, can't we say they is wrong as there is no antecedent of they. Starfish is singular and thus can't be the antecedent.

(A) one arm is lost it quickly replaces it, sometimes by the animal overcompensating and
The pronoun it needs to refer to the same thing. It refers to both starfish and arm in this situation.

(B) one arm is lost it is quickly replaced, with the animal sometimes overcompensating and
Correct - there are no pronoun issues. Compensating is parallel with growing.

(C) they lose one arm they quickly replace it, sometimes by the animal overcompensating,
Sometimes by the animal is awkward

(D) they lose one arm they are quickly replaced, with the animal sometimes overcompensating,
Pronoun issues with they and they

(E) they lose one arm it is quickly replaced, sometimes with the animal overcompensating,
Adverbial modifier issues here with , growing - eliminate

I have a question:
Starfish, with anywhere from five to eight arms, 'have' a strong

Does the prepositional phrase have anything to do with the 'have' here... Starfish have a strong... May mean that strfish is being treated plural here

I eliminated C,D and E for meaning; it just does not make sense to say they lose one arm. One starfish might lose one arm.

(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,


This question is pure test of SVA

Here we have two noun : Starfish and arms
Pronoun : Which is referring is They and It

If we will look closer , Starfish : obviously plural
Arms: Plural

(A) one arm is lost it quickly replaces it, sometimes by the animal overcompensating and

It—> referring to arm ( one arm singular)
Second it: Referring to Starfish???? Not sure. So we can’t go with this opt. And it can’t refer to a plural noun. So Wrong.

(B) one arm is lost it is quickly replaced, with the animal sometimes overcompensating and
It—> referring to arm ( one arm singular)
Sounds weird but grammatically correct.


(C) they lose one arm they quickly replace it, sometimes by the animal overcompensating,

They: Correct referring to Starfish but how arm ( singular) will refer to they?? WRONG

(D) they lose one arm they are quickly replaced, with the animal sometimes overcompensating,

Same issue as C so wrong


(E) they lose one arm it is quickly replaced, sometimes with the animal overcompensating,

This is correct but look at the meaning is changing. they lose one arm it is quickly replaced.

Nice explanation. Was lost in this question.
Now understood.
Thanks.

Attacking point:
1. if ACTIVE, then ACTIVE
OR if pASSIVE then pASSIVE

2. position of adverb frequency "sometimes"
if you find attacking this question on the error "with or by" is rather ambivalance, then attack adverb "sometimes".
*An adverb is a word or phrase that modifies a verb, adjective, another adverb, determiner, noun phrase, clause, preposition, or sentence

if you read the entire sentence, you can gauge the meaning of...

1. ..."sometimes by the animal" overcompensating and growing an extra one or two...
-> "sometimes by the animal" ... and "sometimes by something else" ...

2. ...with the animal "sometimes overcompensating" and "growing" an extra one or two...
sometimes is place next to the verb overcompensating and growing, clearly, it modifies the verb.

-adverbs of frequency-
https://www.thefreedictionary.com/Adver ... quency.htm


(A) one arm is lost it quickly replaces it, sometimes by the animal overcompensating and
one arm is lost (passive) ...it quickly replaces it(active) -OUT-
sometimes by the animal (so sometimes by the animal, sometimes by other animals) -OUT-

(B) one arm is lost it is quickly replaced, with the animal sometimes overcompensating and
one arm is lost (passive) ... it is replaced (passive) -OK-
the animal "sometimes overcompensating" and "sometimes growing an extra" -OK-
1. adverb frequency is place next to overcompensating, clearly modifies overcompensating
2. parallelism growing and overcompensating

(C) they lose one arm they quickly replace it, sometimes by the animal overcompensating,
they lose one arm (active) ... they replace it(active)-OK-
sometimes by the animal (so sometimes by the animal, sometimes by other animals)-OUT-


(D) they lose one arm they are quickly replaced, with the animal sometimes overcompensating,
they lose one arm (active)...they are quickly replaced(passive) -OUT-
with the animal sometimes overcompensating, (Leave this if you find it is "too hot" for you to handle, afterall, you have found major flaw of this question)
"...the animal sometimes overcompensating, growing an extra.."
(it seems growing is modifying the preceding verb"overcompensate" and the subject is the doer. However, overcompensating is not the correct tense. It should not be in simple present continous, rather, simple present tense "compensate".

when to use simple present tense:
To express habits, general truths, repeated actions or unchanging situations, emotions and wishes: ...
1. water boils at 100degree.
2. In the 1983, the sun rise from east to west
3. I eat a bowl of cereal every morning since the day I learn how to eat solid food (my habit)
4. Starfish grow extra arm. (Generally, this is true, not unless some mutations change the habit of starfish.)

To give instructions or directions: ...
To express fixed arrangements, present or future: ...
To express future time, after some conjunctions: after, when, before, as soon as, until:

when to use simple continous tense :
For actions happening now. When we want to talk about an action that is happening now or at this time (and is unfinished), we use the present continuous tense. We also use this tense when we want to make clear that the action is temporary. Sorry, she can't come to the phone right now; she is having a bath.
1. The starfish was attacked by a crab when it was growing an extra arm.
if tense is used wrongly, it is a MAJOR error. So OUT!

(E) they lose one arm it is quickly replaced, sometimes with the animal overcompensating,
they lose one arm(active), it is quickly replaced (passive, you can check with adding "BY" at the end of the sentence "it is quickly replaced "by"...)
-out-
sometimes with the animal overcompensating, growing
if tense is used wrongly, it is a MAJOR error. So OUT!

Ans: B

B has the same problem too according to your explanation for D saying "in a passive voice we need to use by rather than with "

(A) one arm is lost it quickly replaces it, sometimes by the animal overcompensating and -
- Plural antecedent - Here first it refers to the starfish whereas in the starting, we have verb have so starfish is plural and first it is singular therefore plural antecedent error
- Adverb positioning error - when we use sometimes by the animal overcompensating - then we are saying sometimes animals do it sometimes somebody else do it.
(B) one arm is lost it is quickly replaced, with the animal sometimes overcompensating and - seems good
(C) they lose one arm they quickly replace it, sometimes by the animal overcompensating, - Second error of A repeated
(D) they lose one arm they are quickly replaced, with the animal sometimes overcompensating, - Here, what does second they refer to? - it should refer to one arm as one arm is being replaced but it should be singular, not "they". This is also not parallel
(E) they lose one arm it is quickly replaced, sometimes with the animal overcompensating, - Same second mistake as A and first if then clause is not parallel
