Although they are crucially important, a person's total calorie intake is only one of the many factors that determine if their weight will increase or decrease.

it is crucially important, a person's total calorie intake is only one of the many factors that determine whether his or her weight will increase or decrease

it is a crucially important factor, a person's total calorie intake is the only one of many that determines whether his or her weight will increase or decrease

crucially important, a person's total calorie intake is only one of the many factors that determines the increase or decrease in their weight

it is crucially important, a person's total calorie intake is the only one of many factors that determines the increase or decrease in his or her weight



I eliminated the 4th choice above on the basis of the requirement that although should be followed by a clause.
Hope its correct.

that works. be sure to read the official explanation for some other reasons to get rid of D as well..

what's the OA... Imo B,

I rejected C because repetition of "factors" isn't actually required. There is a difference of ONLY ONE OF and THE ONLY ONE OF in B & C but both options make the required change in verb, hence that issue is RED-HERRING. Is there any other reason for ruling out C

"only one of/the only one of" is an important split for meaning reasons:
I am only one of three people in the house.
I am the only one (of three people in my house) who pays rent.

For this reason, we can eliminate C.

Correct answer is B, based on S/V agreement and determine/determines split

A person's total calorie intake is only one of the many factors that determine whether his or her weight will increase or decrease.

"only one of/the only one of" is an important split for meaning reasons:
I am only one of three people in the house.
I am the only one (of three people in my house) who pays rent.

For this reason, we can eliminate C.

i didn't get this meaning difference, please explain w.r.t options B & C

Let's look at an easy example again:
I am ONLY ONE of three people in the house.
Meaning: I am one of the three and there is nothing special about me in relation to the others.

I am THE ONLY ONE of three people in the house who pays rent.
Meaning: I am the only one of the three people to do something. I am special in this aspect compared to the other two.

Let's look at B and C:
B) it is crucially important, a person's total calorie intake is only one of the many factors that determine whether his or her weight will increase or decrease

Meaning: Calorie intake is one factor, but not the only factor, in determining weight.

C) it is a crucially important factor, a person's total calorie intake is the only one of many that determines whether his or her weight will increase or decrease

Meaning: The only factor that matters in determining weight is calorie intake.

I hope that this has helped! :-)

C) it is a crucially important factor, a person's total calorie intake is the only one of many that determines whether his or her weight will increase or decrease

Meaning: The only factor that matters in determining weight is calorie intake.

as per above meaning, isn't C redundant. there is no use of "one of the many" in this case. below sentence says exactly same thing
a person's total calorie intake is the only factor that determines whether his or her weight will increase or decrease

Well, I think that it's more an issue of word economy. It's shorter to say "the only factor" than it is to say "the only one of many".

Hi,

With regards to the explanation for the answer B, I don't understand this part: "Finally, the singular pronoun "his or her" refers correctly to "a person's"."
When I compare it to the SC MGMAT book, the example with "Shakespeare's" (back cover) seems contradictory.

Thanks in advance for your clarification.

I'm happy to discuss the apparent contradiction if you can specify exactly what you think the contradiction is. I'm not just giving you a hard time here; you'll find that articulating what the perceived contradiction is will help you understand my explanation better, if it doesn't resolve your concern entirely. :)
