Hi Ron.. I have a query.. We have generally seen "and also" is wrong in most questions as it is redundant. I have only seen it in the right answer choice of one question. In that question you have explained that "and also" is used whenever we want to point to one person or option...

Hi Ron..

How to identify such modifiers because while solving this question i ruled out the right answer choice considering it a run on sentence

I will give it a try

A. it does not have a antecedent

B. it does not have a antecedent

C. Correct

D. "known to be making" seems as men will make stone tools in future

E. meaning absurd..seems some date of humans

After Despite we need noun or noun phrase
I have seen same construction wrong in some og problem as well "Despite the fact"

Yes we can do this by arrangement. We have three places __ __ __ and we can use odd number(O) or even(E). So we have total 2*2*2 = 8 ways. For getting odd number we need either O,O,O and can arrange in 3!/3! = 1 way or other possible combination for getting sum odd is E,E,O = 3!/2!= 3 ways. Therefor...

I will give it a try:

As whigs is plural, so we need plural verb. Kick out b,c,d.
Left between A and E.
A is not parallel as we need verb, hence E is better

what is OA? is it E

Hi Ron and Stacey.. Thanks a lot for all the help both of you are providing. I gave my GMAT few days back and got a 720(Q-50, V-38). However, I am giving it again in a moth or so. I have two questions. I am very confused 1. When can we use which after comma to stand for the entire clause ......, whi...

Hi.. I will give it a try A. A seems to indicate that theory contributed to the extinction and not fire .. clay deposits has provided new evidence supporting the theory ....that contributed to the extinction B. This seems to be the right option C. Unnecessary usage of that.. Also first that does not...

Not so sure..
But E seems to be better due to usage of infinitive..
In C..
instead of facing -- doesn't seem right as we do not use instead of Verb+ing

Ron please comment

A. Correct
B. Should not be light pulses as original sentence is talking about singular light and light pulse
C. Subj-Verb agreement issue. Should be have caused
D. light pulses should be light pulse
E. Meaning change. Original sentence says caused the light to do so and not enabling it

D has actual few problems (i)it changes meaning meaning of the sentence should be since(because) X, Y and Z put gold... X - erosion, Y - prehistoric glacier movement, Z - gold-bearing riverbeds thrust to the surface by volcanic activity However d says..volcanic activity that thrust ancient, gold-bea...

I don't think we can rule option c out on the basis of "same as the one" is wordy. However... second error you specified seems correct as , enabling is modifying the entire clause and is not conveying the right meaning D seems to be the right option as it conveys the right meaning what is ...

Since can be used in two ways
1) as you correctly mentioned time reference
2) can also be used in place of because

D is wrong for above mentioned reasons
Answer will be E

First of all after a career as First Lady in which she shattered expectations....is a noun modifier and must be followed by Eleanor Roosevelt.. Therefore we can remove B,C and are left with A,D and E A is not parallel in comparison since "in which she shattered expectations " is not parall...
