https://www.youtube.com/watch?v=PmHDJYtdDOkI've come across this question.
Can someone please tell me why we cannot use
"enrollment" here???
I do not understand why \(D \)is wrong...
In below question, we are okay with the usage of
"harvest", but here
"enrollment" is considered wrong??????
https://gmatclub.com/forum/in-1979-lack ... l#p1111413WHY??????
We can compare "41 million tons" to the "harvest", yet we cannot compare "8 million people" to the "enrollment"...Q1:
Quote:
According to a study by the Carnegie Foundation for the Advancement of Teaching, companies in the United States are providing job training and general education for nearly eight million people, about equivalent to the enrollment of the nation’s four-year colleges and universities.
(D) as many as the enrollment of
(E) as many as are enrolled in
I follow very manual approach ( literal reading) when deal with questions related with comparison .
What D says:
nearly eight million people, about
as many as the enrollment of the nation’s four-year colleges and universities.
Here 8 million people are compared with enrollment
What we want:
Compare 8 million people with number of people enrolled
E bridges this gap: you can read B as :
nearly eight million people, about
as many as ( quantity ) (WHO? = people) are enrolled in the nation’s four-year colleges and universities.
nearly eight million people, about
as many as (number of people- ellipsis) are enrolled in the nation’s four-year colleges and universities.
8 million people vs number of people who are enrolled
- Logical comparison; quantity as adjective
Question2:
Quote:
In 1979 lack of rain reduced India's rice production to about 41 million tons, nearly 25 percent less than those of the 1978 harvest.
What we need to compare
41 millions tons ( in 1979) compared with quantity in 1978 -->
quantity comparison; quantity as nounManual read B:
In 1979 lack of rain reduced India's rice production to about 41 million tons, nearly 25 percent
less than the 1978 harvestAsk question: What is 1978 harvest ?
Not clear?
Go backwards:
Production is 41 million tons
41 millions tons ( 1979 number) is 25% less than some number ( 1978)
Can I say:
This number (41 million) is how much quantity was produced in 1978
Similarly , How much for 1979:
In 1979 we harvested xx million tons
Can I say ?
1979 harvest was xx million tons ( quantity).
For your questionsFirst question compares
<number> people : number as adjective
2nd question compares:
a number : number as noun
If 1st question is changed to:
Companies in United States are providing job training and general education to people for nearly eight million, about equivalent to the enrollment of the nation’s four-year colleges and universities.
Now enrollment can be equivalent to quantity .
Original :
8 million people vs number of people enrolled in
Modified: People in quantity vs quantity ; people is common now for both comparison; so comparison is noun vs noun
Another example:
There are 5 people in this room as compared 3 people in that room
Wrong: People in this room are 5 as compared to 3 people in that room.
Production is 41 million in 1979 , 25% below in 1978. (quantity comparison)
Production is 41 million in 1979 , 25% below that (production ) in 1978. (quantity comparison)- what E says
Another approach for Q2: We only have 2 options to choose : 1978 harvest vs 1978
1978 is not clear. It represents year. But 1978 harvest represent harvest in 1978, harvest can be understood as some quantity
I hope it helps
