One study has indicated that if the marriage patterns of 1960 were imported into 2005, the American economy's Gini coefficient—the standard measure of income inequality—would fall to 0.34 from 0.43, a considerable drop given that the scale runs from zero to one.

A) Gini coefficient—the standard measure of income inequality—would fall to 0.34 from 0.43, a considerable drop correct answer

B) Gini coefficient, the standard measure of income inequality, falls to 0.34 from 0.43, a considerable drop - wrong punctuation

C) Gini coefficient—the standard measure of income inequality—will fall to 0.34 from 0.43, a considerable drop - not real situation, should be would

D) Gini coefficient—the standard measure of income inequality—will fall to 0.34 from 0.43, dropping considerably - not real situation, should be would

E) Gini coefficient, the standard measure of income inequality, would fall to 0.34 from 0.43, a considered drop wrong modification

Looks good.

B) Gini coefficient, the standard measure of income inequality, falls to 0.34 from 0.43, a considerable drop

Conditional verb tenses must match..

Imported (in the non-underlined portion) is past tense, so the conditional should be

If the marriage patterns were imported the Gini coefficient would fall.

C) Gini coefficient—the standard measure of income inequality—will fall to 0.34 from 0.43, a considerable drop

Same as (B)

D) Gini coefficient—the standard measure of income inequality—will fall to 0.34 from 0.43, dropping considerably

Same as (B)

E) Gini coefficient, the standard measure of income inequality, would fall to 0.34 from 0.43, a considered drop


"A Considered drop" changes the meaning / Doesn't make sense

Option A is correct.

Would/could is the correct verb form for a simple past "if" usage.

IMO correct answer is A.

A Hypothetical situation demands the usage of "would" so this question is a straight forward 2/3 split between A/E and B/C/D.

In E, the use of "a considered drop " - wrong modification, awkward usage & can be discarded.
Suitable answer choice is A.


One study has indicated that if the marriage patterns of 1960 were imported into 2005, the American economy's Gini coefficient—the standard measure of income inequality—would fall to 0.34 from 0.43, a considerable drop given that the scale runs from zero to one.

A) Gini coefficient—the standard measure of income inequality—would fall to 0.34 from 0.43, a considerable drop - Correct

B) Gini coefficient, the standard measure of income inequality, falls to 0.34 from 0.43, a considerable drop

C) Gini coefficient—the standard measure of income inequality—will fall to 0.34 from 0.43, a considerable drop

D) Gini coefficient—the standard measure of income inequality—will fall to 0.34 from 0.43, dropping considerably

E) Gini coefficient, the standard measure of income inequality, would fall to 0.34 from 0.43, a considered drop

E) Gini coefficient, the standard measure of income inequality, would fall to 0.34 from 0.43, a considered drop

Here is my approach. Initial 5 seconds to skim through first and last word of the underlined sentence and option choices.
Split#1 Comma vs Dash
Since the author is trying to define the term GC, the usage of Dash is appropriate.
Eliminate B and E.
Option D uses the modifier dropping which is not correct here. You can modify the entire defintion since there is no other clause that it can modify.
Option B (and D) uses the helping verb will. It is future tense but it shows 100% certainty of something happening and that is not the case here.
A is a good option as it is. :)

IMO A.

Hello,

Option A is CORRECT, and here is my attempt to explain why. Let us start by deconstructing the sentence and figuring out the meaning, before getting into the options.

Sentence: One study has indicated that if the marriage patterns of 1960 were imported into 2005, the American economy's Gini coefficient—the standard measure of income inequality—would fall to 0.34 from 0.43, a considerable drop given that the scale runs from zero to one.

Meaning: The sentence is basically telling us the possible result of a study that has been conducted. Note that this result need not necessarily be a fact. Keeping this in mind, we're looking for an answer option which tells us that if the marriage patterns of 1960 were imported into 2005, there would be a decrease in the Gini coefficient.

Quote:
A) Gini coefficient—the standard measure of income inequality—would fall to 0.34 from 0.43, a considerable drop
The em dash is perfectly used to explain what the Gini coefficient is, and the usage of the verb phrase 'would fall' tells us that this is a possible result of the given study. This option perfectly matches with our deconstruction of the meaning, so let's hold this one and review the other options.

Quote:
B) Gini coefficient, the standard measure of income inequality, falls to 0.34 from 0.43, a considerable drop
Here, we have a correct modifying phrase for the Gini coefficient, BUT, falls to 0.34 from 0.43? 3rd person usage of 'falls' here is unnecessary. INCORRECT.

Quote:
C) Gini coefficient—the standard measure of income inequality—will fall to 0.34 from 0.43, a considerable drop
Hmm. Looks okay at first, but 'will fall'? The result is merely a prediction, and predictions aren't facts. We can't say for sure that it will fall. It might fall, it might not. INCORRECT.

Quote:
D) Gini coefficient—the standard measure of income inequality—will fall to 0.34 from 0.43, dropping considerably
Same as above, but coupled with the fact that we don't need a gerund here. The sentence wants to say that the drop to 0.34 from 0.43 is of a considerable margin, and this doesn't tell us that. INCORRECT.

Quote:
E) Gini coefficient, the standard measure of income inequality, would fall to 0.34 from 0.43, a considered drop
A rather funny one. A considered drop amongst who exactly? Easily the first candidate for elimination had it not been the last option. INCORRECT.

Option A stands and is CORRECT.

Hope this helps!

Only fight was between A and E ( B,C,D wrong for various other obvious reasons) Both use of --(dash pair) or ,, (comma pair) is correct in A and E. The only difference in the considered in Option E, which one is likely to miss in a exam like setting and fall for the conventional trap.

Why B,C and D are wrong

we have If Condition, then Outcome construction here. If then costrcution need to follow following rules, which are clearly violated in B,C and E

Only following tenses allowed in If-then Construction

1) There are 3 possibilities for if clause
type------------- if-clause ---------- main clause
1----------- Simple Present---------- will-future
2----------- Simple Past--------- would + infinitive
3----------- Past Perfect--------- would + have + past participle
Here it is simple past . So we can eliminate B, C & D.
The answer is A
