Two centuries ago, Tufe Peninsula became separated form the mainland, isolating on the newly formed Tufe Island a population of Turfil sunflowers. This population’s descendants grow to be, on average, 40 centimeters shorter than Turfil sunflowers found on the mainland. Tufe Island is significantly drier than Tufe Peninsula was. So the current average height of Tufe’s Turfil sunflowers is undoubtedly at least partially attributable to changes in Tufe’s environmental conditions.
Which of the following is an assumption on which the argument depends?
A. There are no types of vegetation on Tufe Island that are known to benefit from dry conditions.
B. There were about as many Turfil sunflowers on Tufe Peninsula two centuries ago as there are on Tufe Island today.
C. The mainland’s environment has not changed in ways that have resulted in Turfil sunflowers on the mainland growing to be 40 centimeters taller than they did two centuries ago.
D. The soil on Tufe Island, unlike that on the mainland, lacks important nutrients that help Turfil sunflowers survive and grow tall in a dry environment.
E. The 40-centimeter height difference between the Turfil sunflowers on Tufe Island and those on the mainland is the only difference between the two populations.
OA is C

The answer should be C.
argument says that..
Two centuries ago, Tufe Peninsula became separated form the mainland,...Now the This population’s descendants grow to be, on average, 40 centimeters shorter than Turfil sunflowers found on the mainland. ..
It actually assumes that height of sunflowers on mainland did not increase because of the changes in environment of the mainland. Hence Option C.
Option D is very tempting but is actually wrong.

A. There are no types of vegetation on Tufe Island that are known to benefit from dry conditions. Irrelevant
B. There were about as many Turfil sunflowers on Tufe Peninsula two centuries ago as there are on Tufe Island today. Quantity of Turfil sunflowers doesnt matter
C. The mainland’s environment has not changed in ways that have resulted in Turfil sunflowers on the mainland growing to be 40 centimeters taller than they did two centuries ago. Correct. If mainland environment changed then change in condition on Tufe island will not be contributed to small length of sunflowers
D. The soil on Tufe Island, unlike that on the mainland, lacks important nutrients that help Turfil sunflowers survive and grow tall in a dry environment. Irrelevant. Island was part of the main land
E. The 40-centimeter height difference between the Turfil sunflowers on Tufe Island and those on the mainland is the only difference between the two populations. Irrelevant![Smile :)](./images/smilies/smile.png)

I understand that C makes the most sense out of all the options in context with the argument....However, out of curiosity why D is wrong....I have two reasons for D being the wrong optionsparsh.21 wrote:Two centuries ago, Tufe Peninsula became separated form the mainland, isolating on the newly formed Tufe Island a population of Turfil sunflowers.

OA is C

1. arg talks about the environmental changes and not the content of soil
2.tufe island is a part of tufe mainland....so the nutrients should be the same for both...
Please advise as to which is the correct logic....I wiill personally go for 1 logic
Thanks!

If we negate D, the statement will strengthen the conclusion.sparsh.21 wrote:Two centuries ago, Tufe Peninsula became separated form the mainland, isolating on the newly formed Tufe Island a population of Turfil sunflowers.

Basically, negated form of D says that physical condition, especially soil, are same on both the parts, eliminating the attribution of physical properties in creating the difference in heights.
