comparison is about ellipsis and parallelism. we have to make sure the comparison is clear and logic.

for comparison to be logic, the pattern of comparison must be in parallel form. This mean every phrase of one clause must be paralel with corresponding phrase of the second clause. elipsis can happen but we must maintain that every phrase in one clause must be parallel with corresponding phrase of the second clause.

3 time as many institutions do x as institutions do y
this is correct. and we can cut off insitutions in the second clause. the sentence becomes choice D. still good.
if we write
3 times as many institution do x as those doing y
I can understand
3 times as many institution do x as those doing y do x. (using parallelism, I can infer this sentence and this sentence is wrong).



the takeaway is that for comparison problem, focus on parallelism because parallelism keep comparison clear.

what I do not understand is when we insert "that/those" into comparison ?

the following is from og new books.
Most of the country’s biggest daily newspapers had lower circulation in the six months from October 1995 through March 1996 than a similar period a year earlier.


(A) a similar period

(B) a similar period’s

(C) in a similar period

(D) that in a similar period

(E) that of a similar period

in this problem, many person choose choice D which contain "that" because they think there are 2 kind of circulation. this problem is harder than our problem because both choice C, the official answer and choice D, are parallel. why we do not need "that" in choice D?

I think (pls, correct me if my thinking is incorrect) that we insert in "that/those" when the comparison need to be clear. if the comparison is clear, we do not insert "that/those". we can cut off all similar phrase in the second clause and keep the second compared element.

if there is 1 singular couple, we keep only the second compared element
3 times as much American eat meat as Vietnamese do
if there are 2 couple of comparison, we keep 2 elements of comparison in the second clause
3 time as much american eat meat as Vietnamese eat vegetable. here first couple of comparison is american/vietnamese, the second couple of comparison is eat meat/east vegetable.

we insert "that/those" when the parallelism dose not help make comparison clear. consider

students of Havard business school are more succesful in business world than THOSE of Hanoi business school are.

we can not omit "that/those" when the element of comparison is adjectival position. IS THIS CORRECT.

"that/those" is used when the "that/those" replace the noun which has a modifier. in our above sentece, the modifier is " of Havard business school". in other words, "that/those " is used when we want to compare 2 different nouns ,each of which has different modifiers and when these two noun is in the same circumstance.

if the element of comparison is not in adjectival position but in adverbial position, "that/those can be omit

most persons are stronger today than yesterday

element of comparion is adverb, today/yesterday, "that/those " is omited.

my conclusion is that we use "that/those " only when comparison element is in adjectival position. IS THIS CORRECT? PLS ,HELP

The way I see it is as below. Can experts from this forum confirm this, please?

Kindly correct if I am wrong anywhere. This is very important to help my understanding.

Comparisons using the form as...as typically fall in the below categories:

Comparing the numbers

1. Comparison of two groups doing the same action. (My intention is: Number of Americans who buy pizza= 2*(number of Indians who buy pizza)

Different ways:
Twice as many Americans as Indians buy pizza. (or)
Twice as many Americans buy pizza as Indians. (Here " Indians do" is not mentioned. "do" is in ellipsis.)
Twice as many Americans buy pizaa as Indians do.

2. Comparison of two groups doing different actions. (My intention is: Number of Americans who buy pizza=2*(Num of Indians who buy salad)

Different ways:
Twice as many Americans buy pizza as Indians buy salad. (or)
Twice as many Americans buy pizza as Indians who buy salad. <-- is this correct?

3. Comparison of same group doing different actions. (My intention is: Number of Americans who choclate=2*(Num of Americans who buy pizza)

Different ways:
Twice as many Americans buy chocolate as buy pizza. (Here "those" is in ellipsis) (question in this thread)
Twice as many Americans buy chocolate as those who buy pizza. <--- is this correct?
Twice as many Americans buy chocolate as those that buy pizza <--- is this correct?


Comparing Likelihoods

1. Comparison of likelihood of two groups to do the same action

Different ways:
Americans are twice as likely as Indians to buy pizza. (or)
Americans are twice as likely to buy pizza as Indians. (or) (Here "do" is in ellipsis) <--- is this correct?
Americans are twice as likely to buy pizza as Indians do.

2. Comparison of likelihood of the two groups doing different actions

Different ways:
Americans are twice as likely to buy pizza as Indians are to buy salad.

3. Comparison of likelihood of the same group to do different actions

Different ways:
Americans are twice as likely to buy chocolate as to buy pizza.
Americans are twice as likely to buy chocolate as pizza. <--- is this correct?


Can any expert elaborate on this understanding? It would be extremely helpful.

Could you please elaborate more, as i can see the experts were saying that there is only ||ism error in this sentence but if we correct the ||ism in this sentence then why the Option E is wrong

Hi Gaurav, if we change charging to charge in option E, it would not be wrong.

But given option D and changed option E (both of which would be correct), we would just go with the more concise option: Option D.
