Official ExplanationDeveloped during the voyage of the HMS Beagle,
Charles Darwin’s theory of evolution by natural selection attributed the notable differences in the Galapagos Islands finches to organisms changing physical and behavioral traits over time to adapt to the needs of the environment.
A. Charles Darwin’s theory of evolution by natural selection attributed the notable differences in the Galapagos Islands finches toB. Charles Darwin’s theory of evolution by natural selection attributed the notable differences in the Galapagos Islands finches to result fromC. Charles Darwin’s theory of evolution by natural selection attributed the notable differences in the Galapagos Islands finches to be the result ofD. Charles Darwin, in the theory of evolution by natural selection, attributed the notable differences in the Galapagos Islands finches toE. in the theory of evolution by natural selection, Charles Darwin attributed the notable differences in the Galapagos Islands finches toThis question deals with two issues. The first is the correct use of commas and modifiers. The second is proper idiom format, being “attributed A to B.” Differences within the text are highlighted.
Since idioms tend to be easier to deal with than modifier, let’s start with that. The proper idiom is
“attributed A to B.” Let’s eliminate any options that don’t follow that format. To make it easier to spot, let’s add in the non-underlined end of the sentence:
Charles Darwin’s theory of evolution by natural selection
attributed the notable differences in the Galapagos Islands finches
toCharles Darwin’s theory of evolution by natural selection
attributed the notable differences in the Galapagos Islands finches
to result fromCharles Darwin’s theory of evolution by natural selection
attributed the notable differences in the Galapagos Islands finches
to be the result ofCharles Darwin, in the theory of evolution by natural selection,
attributed the notable differences in the Galapagos Islands finches
to in the theory of evolution by natural selection, Charles Darwin
attributed the notable differences in the Galapagos Islands finches
to We can eliminate options B & C because they don’t follow the “attributed A to B” idiom structure properly. Now that we have it narrowed down to 3 options, let’s tackle our next issue: punctuation and modifiers. First, we need to make sure what immediately follows the modifier phrase “Developed during the voyage of the HMS Beagle” makes sense. Next, we need to make sure the punctuation works. To make mistakes easier to spot, let’s add in that modifier phrase:
A.Developed during the voyage of the HMS Beagle, Charles Darwin’s theory of evolution by natural selection attributed the notable differences in the Galapagos Islands finches toThis is
CORRECT! The modifier makes sense with what comes after it, and we can’t find any other issues with punctuation.
D.Developed during the voyage of the HMS Beagle, Charles Darwin, in the theory of evolution by natural selection, attributed the notable differences in the Galapagos Islands finches toThis is
INCORRECT because Charles Darwin wasn’t developed - his theory was!
E. Developed during the voyage of the HMS Beagle, in the theory of evolution by natural selection, Charles Darwin attributed the notable differences in the Galapagos Islands finches toThis is also
INCORRECT because the modifier is attributed to Charles Darwin, and not his theory. How so? Because the phrase “in the theory of evolution by natural selection” is off-set by commas, making it a non-essential phrase. If you remove it (because you can remove any phrases with this punctuation), the modifier/antecedent pair doesn’t work. By placing that phrase in between the modifier and antecedent, it’s meant to confuse or distract you!
There you have it - option A was the correct choice all along! By focusing on one problem at a time, we can eliminate our options quickly!
