The climate extremes of the North Atlantic nation of Iceland ensure that little plant growth will be able to survive there. The majority of the island is covered in low grasses, with only one tree species known to exist. Deforestation in previous centuries depopulated the entire island of its trees. Because of both the severe cold and the severe heat, plants require a long period of time to grow in Iceland, and modern residents have only just begun replanting the trees. Plant life in Iceland is also notoriously delicate, and off-road vehicles are allowed only in certain areas; in some cases, hikers are required to walk around certain plants to ensure that the plants will survive even during the extreme weather that constantly surrounds Iceland.
Considering the claims below within the context of the passage above, which claim is most likely to be true?
(A) More developed plant growth exists closer to the island’s center, where volcanic warmth allows the plants to survive.
(B) The plants that manage to survive in Iceland are extremely hardy.
(C) The only type of tree capable of growing successfully in Iceland is the northern birch.
(D) Global warming in recent decades has encouraged plant growth, with a corresponding improvement in the development of Icelandic plant life.
(E) Off-road vehicles can cause permanent or long-term damage to the re-growth of some plants.
OFFICIAL EXPLANATION
Overview: Question presents information about the condition of plant growth in Iceland. According to the passage, the Icelandic climate forbids much new plant growth and delays normal plant growth considerably. Apparently, only one species of tree exists in Iceland, because previous residents in past centuries cut down most of the trees, and few have been able to grow back. Additionally, the passage notes that the plant life is exceedingly delicate and that off-road vehicles are not allowed in certain places, while hikers are expected to avoid stepping on certain plants. The question asks the student to identify which of the answer choices is most correct given the statements made in the passage. The student is essentially being asked to make an inference. Note that this question does not ask for the main point of the passage, so the statement that is correctly inferred will not necessarily be the primary focus of the passage; it will simply be something that can be deduced from what is stated in the passage.
The Correct Answer:E Of all the answer choices, answer choice (E) is the only one that can correctly be inferred from the information in the passage. The author states that “little plant growth will be able to survive” in Iceland, that “plants require a long period of time to grow in Iceland,” and that “the plant life in Iceland is also notoriously delicate.” This suggests that off-road vehicles have the potential to destroy plant life, leaving plants unable to grow back for long periods of time or, in some cases, unable to grow back at all. Therefore, answer choice (E) is correct.
The Incorrect Answers:A The passage notes quite explicitly, “Because of both the severe cold and the severe heat, plants require a long period of time to grow in Iceland.” This indicates that the extreme heat of the volcanoes would not encourage plants to grow any better than the extreme cold of other parts of Iceland. Answer choice (A) is incorrect.
B The passage states that the plant life is “notoriously delicate” and that it takes years for plants to grow back. Answer choice (B) contradicts this, so it cannot be correct. Therefore, answer choice (B) can be eliminated immediately.
C The passage does state that one species of tree survives in Iceland, but it does not identify that species or imply what it might be. (Although the northern birch is the only tree species to grow in Iceland currently, the passage does not imply this.) Answer choice (C) is incorrect.
D Although the information in answer choice (D) might be accurate, there is nothing in the passage to suggest that it is. The passage notes only that Iceland’s climate forbids extensive plant growth and that plants can take a very long time to grow. Therefore, the details in answer choice (C) cannot be inferred from the passage, so it must be eliminated. Answer choice (C) is clearly incorrect
