The speculative fever of the Roaring Twenties infected rich and poor alike; vast quantities of people were dangerously overextended, credit was absurdly easy to obtain, and most brokerage houses required only ten percent cash for stocks bought on “margin.”

I could be wrong, please post OA.

The spraying of pesticides can be carefully planned, but accidents, weather conditions that could not be foreseen, and pilot errors often cause much larger deposits of spray than they had anticipated.
(A) weather conditions that could not be foreseen, and pilot errors often cause much larger deposits of spray than they had

(C) unforeseeable weather conditions, and pilot errors are the cause of much larger deposits of spray than they had
(D) weather conditions that are not foreseeable, and pilot errors often cause much larger deposits of spray than

I will go with C. Its parallel and having a followin senetence struct.

Independent Clause + but + Independent Clause + than + dependent clause.

I am not sure about 'they' though. It looks funny. what happened to Option E?

I think all the adjectives modifying people are wrong. I eliminated the A,B,C based on idiom both x and y

A but X,Y and Z

X, Y and Z should be parallel. A,B and D None of the answers have this structure. Hence incorrect.

In C, they does not have a correct referrent
What is option E?

(A) rich and poor alike; vast quantities of people were dangerously overextended
quantity for uncountable noun

(B) both rich and poor alike; large amounts of people dangerously overextended themselves
both x and y alike...alike is redundant...also large amount ...uncountable

(C) rich and poor alike; great numbers of people were dangerously overextended

Correct..but Numbers of ........always wrong as said manhattan....
Don't know who is right manhattan or the question Creator!!

(D) both rich and poor alike; vast amounts of people dangerously overextended themselves
amount---- uncountable

(E) both rich and poor; great quantities of people were dangerously overextended

The science of economics << Main subject >> , which for four decades was dominated by Keynesians << First Relative clause>>, who at first stressed the government’s role in stimulating the economy, but who were ultimately led away from solutions based on government intervention << Second Relative clause>>. .

Ok I got your point.

you are sying that there is no main clause and three relative clauses.

thanks

I think you can elimate A and C just b/c the tenses don't seem to match.
The spraying of pesticides can be carefully planned (can be = future)
choices that end with THEY HAD refers to PAST tense . The tenses don't agree.

The science of economics, which for four decades was dominated by Keynesians, who at first stressed the government’s role in stimulating the economy, but who were ultimately led away from solutions based on government intervention.

(A) economics, which for four decades was
(B) economics that was to be
(C) economics, one which has, for four decades, been
(D) economics is one that for four decades has been
(E) economics, for four decades, is one that was

I have this set of 1000SC's which says OA-D and in the post above the OA is given to be E(which i find absolutely awkward!)

I believe we need "which" to introduce a relative clause
IMO-C
