I d go with A and C....I had difficulty in the first SC - ultimately went for A after a long thought

[karanrulz4ever]

1) A. C and D are out as they suggest that the atmosphere is affecting.E wrongly uses "as". A is clearer version as compared to B.I also feel B is slightly wordy.
2) C .Employs "such as" and "remains" properly.

[winner's attitude]

Answer of Both are C

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 effect global climate.

A. atmosphere, interaction that affect == affect is wrong
B. atmosphere, with interactions affecting == wordy
C. atmosphere that affects === Correct, because the data between x and y affect the global climate
D. atmosphere that is affecting == wrong tense
E. atmosphere as affects == no clarity

I am just a learner, so i could be wrong in above explanation , pls feel free to correct me if i am wrong.

The market for recycled commodities like aluminum and other meals remain strong despite economic changes in the recycling industry
A. commodities like aluminum and other metals remain
B. commodities like those of aluminum and other metals are remaining
C. commodities such as aluminum and other metals remains
D. commodities, such as aluminum and other metals, remain
E. commodities, like the commodities of aluminum and other metals, remains

First let us understand the logic in this question. What effects global climate? The ocean or the atmosphere or the interaction between the two? As stated in the non-underlined part of the sentence it is the interactions.[spoiler] Thus A is a winner.[/spoiler]
B - wordy due to the 'with"
C - makes reference to 'atmosphere' effecting the global climate, hence meaning changed
D - Same as above
E - meaning change

Second sentence, to introduce examples use "such as". Thus C and D remain. What remains / remain strong? The market which is singular hence [spoiler]choose C.[/spoiler] Also the commas in D are unnecessary.

Hope this helps!

hei , THERE IS A TYPO"INTERACTION" BETWEEN ORIGINAL SENTENCE AND OPTION 1.
@ VERONICA =PLZ PAY ATTENTION WHILE YOU POST UR QUESTION
THANKS.

To the curious, in the first question, choice A effectively uses something called a resumptive modifier. - interactions that effect global climate

Resumptive modifier is a type of appositive which repeats a key noun (in our case, interactions), verb, or adjective and then resumes the line of thought, elaborating on what went before.
