explanation:
option 1: wrong use of 'to' before how,usage of 'as' is not proper
option 2,3:repeating above mistake along with wordiness
option4: correct.
'without' acts as a preposition and is folowed by noun.
'as' acts as conjunction and suordinate clause follows it.
option5:wrong use of 'to' before how
ans: option 4

It seemed that hardly any vote was cast on the Senate or House floor without some calculation as to how it might affect the midterm election.
A. without some calculation as to how
B. without there is some calculation as to how
C. without that there is some calculation as to how
D. without some calculation as how
E. without some calculation to how

Solve & Explain..
OA

Its a tougie.

B, C are naturally out as they are too wordy.

'A' does sound correct.. but unable to determine any rule as to why D,E are incorrect :( ..

Experts, please help!

A is concise and 'as to how' is idiomatic.

Guys,
without some calculation is a prepositional phrase, thus will modify Floor.So how can the floor be without any calculation?
For example.
I read the book on the table
on the table is a prepositional phrase that modifies book

Please clarify

as is used because it introduces a clause "to how it might affect the midterm election." affect is the verb in the clause. As such, you have to include "as" before the "to".

I choosed D, but A seems to be correct also.

As to is idiom meaning "with regard to, concerning, according to".

But why should we use to before how? I am not sure if it changes the meaning of the sentense.

To me, Some calculation as ____

As implies like hence doesn't convey the intended meaning


I am unable to figure out the grammatical err in E though I know it "sounds" wrong or awkward

IMO, ‘as to’ is an acceptable idiom, as per the freedictionary.com. Between A and D, I do not favor D since as how starts a process of comparison, which is not what the topic intends.

B is redundant, because of the usage of without there is.
C without that there is redundant too
D as how is awkward

Between A and E calculation as to how sounds better. Answer A :D
