Darth,
In this sentence I think the subject of the main phrase .."interactions" need not be repeated again at the at the start of the modifier modifier..
A...interactions between the ocean and the atmosphere, interactions that affect global climate
The sentence is in present indefinite form....keeping this throughout
I think we can safely bank on C ..atmosphere that affects....that is antecedent to interactions..
What's the OA..

I take back my give ... :-P...I have not noticed the plural form of the subject in question..in that case ..darth should be right..
sorry about my folly..

I would not wanna post my understaning about the other 2.. lets just take 3rd one into consideration in here ;)

Floating in the waters of the equatorial Pacific, an array of buoys collects and transmits data on long-term interactions between the ocean and the atmosphere, interactions that affect global climate.
A. atmosphere, interactions that affect
B. atmosphere, with interactions affecting
C. atmosphere that affects
D. atmosphere that is affecting
E. atmosphere as affects


Floating in the waters of the equatorial Pacific, an array of buoys collects and transmits data on long-term interactions between the ocean and the ________ global climate.

NOTE
an array of buoys collects and transmits data on long-term interactions between the ocean and the -

array = singular = carrying multiple interactions

interactions between the ocean and the = Plural

we surely know that the first word is 'atmosphere', so we have;


Floating in the waters of the equatorial Pacific, an array of buoys collects and transmits data on long-term interactions between the ocean and the
atmosphere ________ global climate.

A. atmosphere, interactions that affect - fill in the blank space and see..an array of buoys collects and transmits data on long-term interactions, INTERACTIONS THAT AFFECT GLOBAL CLIMATE - MAKES COMPLETE SENSE
B. atmosphere, with interactions affecting - AWKWARD SENTENCE
C. atmosphere that affects - NO CLEAR MEANING.. "that" refers to what..??.. AFFECTS is SINGULAR, "INTERACTIONS" is PLURAL
D. atmosphere that is affecting - INETRACTIONS ARE AFFECTING CLIMATE, NOT THE ATMOSPHERE.. also "INTERACTIONS" is PLURAL
E. atmosphere as affects - NO MEANING AT ALL

hope this helps ;)

Siddharth and Darth Maul,

Awesome discussion here friends. And you both brought up a very important and subtle issue.

Without the "comma" "pre-columbian ownership" and "communal ownership" could not be related to each other. It is possible to missinterpret them as two separate forms of ownership. The "comma" qualifies the sentence to convey the meaning that: "propose a return to communal ownership..(which is nothing but) the pre-columbian ownership once respected by Spainiards."

None of the other choices relays this subtle relationship.

Look at the following 2 sentences. Please tell me if both are correct or not.

a)Upon leaving the register, the customer received a receipt from the cashier.

b)The customer received a receipt from the cashier,upon leaving the register.

The modifier always modifies the subject of the preceding clause,rt?. HEnce in both the above cases it modifier the customer. (which is what is intended).
hence both a& b are correct?.

B conveys the meaning that the "cashier" is leaving the register.
A is precise IMO.

I think in b) it appears that the cashier left the register, this changes the meaning of the sentence. Unless there is a real reason to separate the noun and the modifier we should not separate them.

Hey Vik, Appreciate it..

but the sentence echoes a contrast between 2 types of land ownership thru the 'propose to' idiom..

the revolutionaries want to overthrow pre-columbine ownership (currently existing -which is respected by the Spanish invaders) and bring in communal ownership (which had earlier existed - I say earlier existed as indicated by 'return to') ..As for the comma, I am speculating, to clearly mark out the phrase that states the proposal.. as there is a 'to' in this phrase.. which could be mistaken for the 'to' in the idiom.

Here 'Upon leaving the register' is a adverbial phrase(answers when the customer recieved a reciept) which can be moved around unlike adjectives(or adjectival phrases)

So both of them are correct. But I won't say it modifies the customer.. it modifies the verb 'recieved'

In fact it could be placed between the subject and the object

c) The customer, upon leaving the register, received a receipt from the cashier.

My response in color.
I will be more than happy to explain if anyone would like me to.
