IMO A. But I am so uncertain on the answer.

One more question. May I ask whether "the number ... rose to 27.5m people (no people)" is better than "the number ... rose to 27.5m people"? Because the subject is "number". A number could rise/ drop but should not have an unit.

Quote:
The UN’s High Commission for Refugees (UNHCR) indicates that while there was a slight decrease in the number of refugees at the end of 2009, the number of internally displaced people within their own countries rose up to 27.5 million people by the end of 2010.

A and C use "by the end" while C,D and E use "at the end". "by the end" should be right because the increase should be gradual throughout the period instead of a sudden jump at the end of 2010. Drop C,D and E.

A) the number of internally displaced people within their own countries rose up to 27.5 million people by the end of 2010
"their" refer to the "people", which is a plural noun. ok.

B) the number of internally displaced people rose to 27.5 million people at the end of 2010
Dropped.

C) the number of internally displaced people increased to an amplified 27.5 million people by the end of 2010
"increased to" and "amplified" have duplicated meaning.


D) the number of displaced people within their own countries rose to 27.5 million people at the end of 2010
Dropped.

E) the internally exiled number of people increased to 27.5 million people at the end of 2010
Dropped.

Hi generis,

I had narrowed down to B and D, but chose D.

Isn't internally displaced a bit vague. Internally displaced from where? country, continent or maybe an island! Could be anything, right?

Compared to that, option D specifies that bit, so clarity over concision?

Could you please help.

Thanks in advance!

PS: I have been going through a lot of your posts, terrific work! Big fan now.

OFFICIAL EXPLANATION

Project SC Butler: Sentence Correction (SC1)


THE PROMPT
The UN’s High Commission for Refugees (UNHCR) indicates that while there was a slight decrease in the number of refugees at the end of 2009, the number of internally displaced people within their own countries rose up to 27.5 million people by the end of 2010.

THE OPTIONS
Quote:
A) the number of internally displaced people within their own countries rose up to 27.5 million people by the end of 2010
Internally and within their own countries are redundant.
Internally displaced already implies that they are displaced within their own countries.

• Idiomatically, we say that something increased to, grew to, or rose to a certain number.
Leave the word up out of the phrasing.
-- We do not say rose up to 27.5 million. The phrasing is awkward at best.
The phrasing also can imply the wrong math: did the number of people increase BY nearly 28 million (to, say, 200 million)? Or did total number itself, after increasing by XYZ amount, nearly reach 28 million?
ELIMINATE A

Quote:
B) the number of internally displaced people rose to 27.5 million people at the end of 2010

• I do not see any errors
KEEP

Quote:
C) the number of internally displaced people increased to an amplified 27.5 million people by the end of 2010
increased and amplified are redundant. At the least, "amplified" is superfluous.

• If I had not yet read option B, to which this option is inferior, I would keep option C and look for a better answer. As the matter stands, though, I can compare (B) and (C). Option B, unplagued by redundancy, is better than option C.
ELIMINATE C

Quote:
D) the number of displaced people within their own countries rose to 27.5 million people at the end of 2010
• the sentence is grammatical. Now what?

→ Compare to option B.
B: the number of internally displaced people
D: the number of displaced people within their own countries
-- internally displaced people is more concise and straightforward than the number of displaced people within their own countries
Option B says the same thing as D says, but B uses fewer words to say the same thing.

ELIMINATE D

Quote:
E) the internally exiled number of people increased to 27.5 million people at the end of 2010
• the modifier internally exiled
(1) seems oddly to modify number rather than people (why not just say "the number of internally exiled people"?)
and
(2) is almost oxymoronic.
→ To exile a person is to expel them from their country.
How can they be inside and outside their country at the same time?
Internally displaced in option B is much more logical.
ELIMINATE E

The best answer is B.

Nice catch!

I think you are correct and that the sentences would all be better if they stated, "The number of internally displaced people rose to 27.5 million."
In this context,
the number [of displaced persons] = 27.5 million
rather than
the number of displaced persons = 27.5 million displaced persons
Nice work!

And it is always a good day (or night) when my good friend pushpitkc joins in.
pushpitkc , I'm so glad to see you over here in SC!
He used to scare the daylights out of me on the PS thread—until I, too, became a PS moderator, and we became friends.

This question is one in which it is SO tempting to choose the correct answer rather than have to explain what is wrong with the other four.
You two did well. Nicely done.

Be safe![/quote]


Hi, in your explanation you have not pointed out the error brought about by the usage of "by the end..." This use would indicate the need for a past perfect tense, or am I wrong here?
