Ms. Chambers is among the forecasters who predict that the rate of addition to arable lands will drop while  those of loss rise ,

(A) those of loss rise
(B) it rises for loss
(C) those of losses rise
(D) the rate of loss rises
(E) there are rises for the rate of loss

daagh · Accepted Answer

D is certainly the choice.

But the reason of elimination of choices B is slightly off IMO.

1. B. There is no ambiguity about the antecedence of ‘ it  ‘. After all,  the rate  is the only singular noun on the text and it can not refer to any thing else and that is the right antecedent. One can not argue, it stands for addition becos, it makes no sense to say that  addition rises for loss .

But B is wrong because of llism. The rate of addition uses an  of  preposition while it rises for loss uses a  for  preposition.

24. Ms. Chambers is among the forecasters who predict that the rate of addition to arable lands will drop while  those of loss rise. 
(A) those of loss rise
 'those' has no reference 
(B) it rises for loss
 'it' has no reference 
(C) those of losses rise
 'those' has no reference 
(D) the rate of loss rises
 parallel and correct 
(E) there are rises for the rate of loss
 'there are rises' is wordy and redundant

mbunny · Answer

D it is!!

The rate is singular. Immediately elminate A, C and E.
That leaves B and D. B has modifer problem, not clear what "it" is referring to. D is the winner.

hirendhanak · Answer

"D" seems most obvious choice on two counts

1) the rate of xyz is singular.
2) E is redundant and B has unclear antecedent IT

pls feel free to correct me if i am wrong

thanks

hirendhanak · Answer

thanks very much... i always mess up when it comes to understanding the rules of how to identify whether IT refers to which antecedent

Can you help me with concrete check points which can give me an idea abt IT's antecedent ( if possible with example ) it will be a great help

thanks in advance

daagh · Answer

1. This is an OG question. You may see no choice contains the 'will rise' option. So, this must be an acceptable version. In some connotations, even the simple present may stand for future events. Like, the school reopens middle of next, month or Hilary is expected to run for the Prez in 2016. 
2. There is also a view that only when we use the fanboy connector ‘and’ should we really look for strict physical //ism, such as in this case, 'will drop and will rise'. But when we use the subordinate connector while, we can still validly use the present tense rises.

honchos · Answer

The Rate  is singular hence   rise   is wrong,   rises   is correct.

E is absolutely redundant and hence  D  wins .

D also maintains Parallelism.

mejia401 · Answer

(A) those of loss rise   Wrong - "those...rise" is not consistent with singular referent, rate 
(B) it rises for loss   Wrong - "for loss" is not structurally similar to "of addition" 
(C) those of losses rise   Wrong - "those...rise" is not consistent with singular referent, rate  
(D) the rate of loss rises   Correct  
(E) there are rises for the rate of loss   Wrong - inverted sentence structure is unneeded and not structurally similar to the "rate of addition"

IMO D

vishuyadav · Answer

64. Ms. Chambers is among the forecasters 
 who predict that 
 the rate of addition to arable lands will drop 
 while those of loss rise.

(A)  those  of loss rise ->  No antecedent for pronoun those  
(B)  it  rises for loss -- >  in comparison when ”it” appear with second entity it denote exactly the same antecedent in this case it refer to “the rate of addition” which makes nonsensical statement. 
(C)  those  of losses rise -->  same as choice A  
 (D) the rate of loss rises -->  Correct (the Rate ... rises )  
(E)  there are rises for  the rate of loss --  Wordy and unidiomatic

Vizy · Answer

Can someone explain the issue with timing in this sentence please?

Is it ok to use Future (will drop) with Present (rises) in this context? Is the part "while the rate of loss rises" already out of "prediction"?

him1985 · Answer

Yes , it is an Idiom

X will rise , while Y rises

HalaMadrid · Answer

Shouldn't it be " the rate of x will drop... while the rate of y will rise" and not rises? Thank you!

Sunil01 · Answer

hi,

agrees 'the rate' is singular, but how in non underline portion 'the rate' is plural.
'the rate of addition to arable lands will drop'
drop is plural and is referring to 'the rate'

experts please help.

Thanks & regards,
Sunil01

sayantanc2k · Answer

No, "drop" is not plural here - the verb is "will drop" which may be singular or plural. "It will drops" is wrong.

Ruigr3 · Answer

Hey guys.
Can anybody explain why we do not use future tense? lands  will drop  while the rate of loss  rises

Thank you

sayantanc2k · Answer

This usage is called future conditional - such usage is also observed in  if  and  when  clauses:

If I  eat  Pizza , I shall fall sick.
I shall talk to you  when I  have  time .

Similarly,
The rate of addition to arable lands will drop  while the rate of loss  rises  .

Ms. Chambers is among the forecasters who predict that the rate of addition to arable lands will drop while  those of loss rise.

Issue:  Pronoun | Meaning

Analysis:
 1. The non-underlined portion of the sentence talks about  "rate of addition" . Hence the subject in the modifier clause  "that the rate.."   is singular.
2. For correct compare comparison, "rate of X" should be compared "rate for Y"

(A) those  of loss rise -  Plural pronoun has no referent 
 (B) it  rises for loss -  "it" is ambiguous 
 (C) those  of losses rise -  Plural pronoun has no referent 
 (D) the rate of loss rises 
 (E) there are  rises for the rate of loss -  "the rate of addition.." is not parallel with "there are rises..."

Answer:  (D)

Skywalker18 · Answer

Ms. Chambers is among the forecasters who predict that the rate of addition to arable lands will drop while  those of loss rise. 
(A) those of loss rise -- those should logically refer to rate but those is plural whereas rate is singular
(B) it rises for loss -- it refers to rate of addition to arable lands --> illogical 
(C) those of losses rise -- same as A
(D) the rate of loss rises -- Correct
(E) there are rises for the rate of loss -- wordy and redundant

Answer D

irishiraj87 · Answer

I will add another angle. 
Rate of means - measuring rate something like Repo Rate etc. whereas Rate for means - what is the charge of something. E.g. What is the rate for 10gms of Gold.

So a subtle difference in meaning can alse be seen.
