OFFICIAL EXPLANATION

Project SC Butler: Sentence Correction (SC2)




In statistics the term "validity" denotes the extent to which an instrument is measuring what it is supposed to measure.

Quote:
A) to which an instrument is measuring that which it is supposed to measure
→ extent to which is idiomatic.
It means "how much" GMAC tests the idiom.
→ But "is measuring that which" sounds stiff, formal, and wordy
KEEP, but look for a better answer

Quote:
B) to which an instrument measures what it is supposed to measure

→ I see no errors.
→ to which is idiomatic
→ no strange "it is" phrases are floating around
→ this option displays the clearest and least tortured language.
KEEP B, ELIMINATE A
Quote:
C) that an instrument is measuring what it is supposed to measure

→ extent that is not idiomatic in this context.
→ when we state facts or talk about general truths, we use simple present tense, not the present progressive tense is measuring
ELIMINATE C
Quote:
D) of [AN] instrument measuring what it is supposed to measure

→ extent OF is not idiomatic in this context.
→ the word AN is missing (AN instrument).
→ the simple present measures is more appropriate for a fact assertion than is measuring
ELIMINATE D
Quote:
E) of the measuring of an instrument is what it is supposed to measure

→ Wow, that sentence is horrible.
→ The words are nonsensical.
-- extent of is not idiomatic in this context
-- the measuring does not stay with the "simple present to report facts" structure
→ this group of words is just nonsense: is what it is
ELIMINATE E

The answer is B

COMMENTS

DeepakKumar24 , welcome to SC Butler.

I think I used up all my random comments in my other OE here.
I talked about indigenous peoples, books, and beer.

Most of these answers are outstanding. Nice work.

D) of instrument measuring what it is supposed to measure

E) of the measuring of an instrument is what it is supposed to measure


A) to which an instrument is measuring that which it is supposed to measure- the word measuring is wrong, and "that which it is" is gramatically incorrect.

B) to which an instrument measures what it is supposed to measure.-"extent to" is the correct idiom, and the seems right. we can keep this.

C) that an instrument is measuring what it is supposed to measure.-"extent that" is unidiomatic, usage of measuring is wrong.

D) of instrument measuring what it is supposed to measure.-" Extent of" , not the correct idiom(I guess). Measuring is also wrong.

E) of the measuring of an instrument is what it is supposed to measure.- Same as D.

IMO B.
Please correct me if I am wrong.

In statistics the term "validity" denotes the extent to which an instrument is measuring what it is supposed to measure.

A) to which an instrument is measuring that which it is supposed to measure // that and which together is awkward.

B) to which an instrument measures what it is supposed to measure // seems fine

C) that an instrument is measuring what it is supposed to measure // continuous tense is not logical. extent that it is measuring what it is supposed to measure is not meaningful.

D) of instrument measuring what it is supposed to measure // validity is an extent of an instrument?? haha. funny. plus an is missing before instrument.

E) of the measuring of an instrument is what it is supposed to measure // very confusing sentence.


Footnote: I have the exam tomorrow. Wish me good luck.

A) to which an instrument is measuring that which it is supposed to measure

=> We need to use simple present as the later portion of the sentence gives us general information

B) to which an instrument measures what it is supposed to measure

C) that an instrument is measuring what it is supposed to measure

=> An instrument is not measuring at this moment.We need to use simple present as the later portion of the sentence gives us general information

D) of instrument measuring what it is supposed to measure

=> This portion 'extent of instrument measuring' creates ambiguity. The modifier 'measuring' modifies what? Does it modify instrument or extent of instrument? Not sure. Actually the modifier should modify 'an instrument'

E) of the measuring of an instrument is what it is supposed to measure

=> Wordy
=> Fragment sentence. the term "validity" denotes the extent...is (what is the subject of the verb is? Is it validity or the extent? )

A: Not sure why continuous tense is required
B: No particular grammar or meaning error
C. Same as 'A'. Although I don't particularly have a problem with the use of 'that', to which sounds more idiomatic to me. Use of continuous tense is a bigger problem here.
D. Horrible choice, distorts the meaning.
E: A lot of issues with this one: usage of continuous tense, distorts the meaning, wordy for no reason.

B is our winner.

The sentence gives factual information, so simple present tense should be used, and "extent to" is the correct idiom.

In statistics the term "validity" denotes the extent to which an instrument is measuring what it is supposed to measure.

A) to which an instrument is measuring that which it is supposed to measure----> Use of present continuous tense is inappropriate

B) to which an instrument measures what it is supposed to measure ----> Correct

C) that an instrument is measuring what it is supposed to measure --> Repeating tense error.

D) of instrument measuring what it is supposed to measure ---> Extent of is not the correct idiom

E) of the measuring of an instrument is what it is supposed to measure. -----> Extent of is not the correct idiom.

A) to which an instrument is measuring that which it is supposed to measure. : We do not need a present continuous tense, This looks like a simple definition and hence we should have a simple present tense here. Plus " that which it is" makes it muss less desirable

B) to which an instrument measures what it is supposed to measure : looks good for now , Lets keep it

C) that an instrument is measuring what it is supposed to measure: "that an instrument is measuring" sounds like validity denotes the "extent that the instrument is measuring" as a physical quantity and not as a measure

D) of instrument measuring what it is supposed to measure : "extent of instrument measuring" sounds like a wrong idiom. Also there is a missing "an"

E) of the measuring of an instrument is what it is supposed to measure : same pb as D, also this just sounds plain awkward and senseless

In statistics the term "validity" denotes the extent to which an instrument is measuring what it is supposed to measure.

A) to which an instrument is measuring that which it is supposed to measure - Since it's a general fact, simple present should be used. Measuring is wrong. Incorrect.

B) to which an instrument measures what it is supposed to measure - Concise. Uses simple present. Correct.

C) that an instrument is measuring what it is supposed to measure - Extent to is the right idiom. Incorrect.

D) of instrument measuring what it is supposed to measure - Extent to is the right idiom. Incorrect.

E) of the measuring of an instrument is what it is supposed to measure - Extent to is the right idiom. Incorrect.

Hence, the answer is Option (B).
