Descending approximately 4,000 years ago from the African wildcat, it has been an exceedingly short time for the domestic cat with respect to genetic evolution and it scarcely seems sufficient to allow the marked physical changes that transformed the animal.

The domestic cat descended from the African wildcat approximately 4,000 years ago, an exceedingly recent divergence with respect to genetic evolution and one which scarcely seems sufficient to allow the marked physical changes in the animal.

Isn't the it/its in A C D ambiguous as it can refer to either cat? I ruled out A,C D based on that

Between B & E, B uses which clearly refers to 4000 years ago and is logically parallel in referring to the same 4000 years ago

E actually uses new words divergence etc..

My pick is B

IMO E for this one

was stuck between D and E on this one

but D although corrects the initial modifier problem, introduces another modifier issue

I think E is the correct answer on this one

i agree with B as well, it properly structures the sentence such that 4000 is an exceeding short period of time for genetic evolution

A,C,D --out It has no clear referrent.
B -- which modifes "ago" (400 years ago) ---not correct.

E wins.

The original sentence begins with a misplaced modifier. It is the domestic cat that descended from the wildcat. We need to find a choice that expresses this correctly.

• (A) This choice is the same as the original sentence.
• (B) The original modifier issue has been corrected. However, the phrase "which is an exceedingly short time" has no referent ("4,000 years ago" is not a time span but a specific moment). so here it implies 4000 years ago is a short time span for evolution which doesn't make sense.
• (C) The original modifier issue has been corrected. However, the phrase "has been scarcely sufficient..." incorrectly refers to the domestic cat.
• (D) The original modifier issue has been corrected. However, the phrase "that has scarcely been sufficient..." incorrectly modifies "genetic evolution". Also "the marked physical changes that transformed the animal" is redundant. Compare to E: "the marked physical changes in the animal," a much tighter way of conveying the same information.
• (E) CORRECT. This choice correctly rearranges the opening modifier to place the words "the domestic cat" immediately next to the modifier "descended from the African wildcat."

Can anyone help me with the usage of "descended from"
According to another question, the right usage should be "is descended from", as "descended from" means a literal down stepping.

in this question the right answer uses "descended from", which would be non nonsensical.

This is the question i'm referring to. Answer is E

Australian embryologists have found evidence that suggests that the elephant is descended from an aquatic animal, and its trunk originally evolved as a kind of snorkel.
A. that suggests that the elephant is descended from an aquatic animal, and its trunk originally evolved
B. that has suggested the elephant descended from an aquatic animal, its trunk originally evolving
C. suggesting that the elephant had descended from an aquatic animal with its trunk originally evolving
D. to suggest that the elephant has descended from an aquatic animal and its trunk originally evolved
E. to suggest that the elephant is descended from an aquatic animal and that its trunk originally evolved

Hi,
There are three usages, which I can think of immediately--
a) descended-- when used alone, literally means to come down from
example:- he descended the staircase..
b) descended from something-- when we want to say how something has evolved/developed/origined
example the Hindu traditions descended from the Bhagwat Gita.
c) Be descended from- a relation with some past ancestors/something
This is the exact usage here, which tells us that th elephant has this ancient animal as his ancestors..

Option B is incorrect in the above question, as it says the elephants literally came down. This is the same issue here

I'd love to post on manhattan, but for some reason I'm not allowed to.
Anyway, this is a response from ron purewal from mgmat regarding the issue with B

--------------------------------------------------------------------------
in B, why " , its trunk originally involving..." is wrong.

i don't think the problem is with that phrase.
two other elements of that answer choice are problematic:
* "has suggested" --> this is the present perfect, which is used to look back on past events that have some sort of relation to the present situation. so, "has suggested" would signify that, at some point in the (probably recent) past, this evidence has suggested what is stated here -- but that it doesn't suggest those notions anymore.
* "descended" (without "is") --> if you mean to state an evolutionary relationship, you should use "is descended". "descended", used alone, signifies literal downward motion.

-----------------------------------------------

Also, on a side note, this is what the dictionary meaning is :

be a blood relative of (a specified ancestor).

"he is descended from a Flemish family"

hi,
B is wrong for two reasons
1) descended from --- very reason you are mentioning
2) usage of ' its trunk originally evolving' is also incorrect

if B is wrong for the reason that it uses descended from, then how is option E correct in the original question of this thread. It also uses "descended from"

" The domestic cat descended from the African wildcat approximately 4,000 years ago, "

I have used the question for reference to pinpoint the error in this thread's question.
Thanks

hi,
I believe the reason here is--
1)the domestic cat descended from african wild cat means the domestic cat has evolved out of african wild cat..
and at present both the animals in Q are present so MAY be the domestic cat 'evolved from' african wild cat is better than ' african wild cat is ancestor of the domestic cat'
2)Had you wanted to say it evolved out of something extinct now, say A..
then it would be better to say the domestic cat is descended from A..

Alright, but by saying the car descended, don't we mean that it had a downward motion? At least that's what mgmat and the dictionary says

Hi rahul
That's exactly what I have written two three posts above...
Descended without from means what is being said
Pl refer my first post after your query..

Chetan, I'm not sure whether u get my point. According to the mgmat post and the dictionary, saying " x descended from y" means that x came down from y. Which is what is pointed out in the question about the elephant. " the elephant descended from", hence it is wrong because the elephant did not come down from anything. The question about the African cat says that the car descended from, which means that the cat came down from something. Which is wrong as pointed out in the question about the elephant

Hi,
You have mentioned car descended so didn't know that you meant cat ...
I think descended from is better used in terms of evolution...
And all these OG examples point towards that.
Can you reproduce the words od mgmat
