While black or green tea tends to be the leaf of choice among connoisseurs, recent studies have indicated there are significant benefits to drinking white tea. White tea is considerably more delicate and rarer than black or green tea and has fewer producers. Because it is unprocessed and unfermented, white tea has very high levels of catechins, which are known for having antibiotic qualities and delaying aging. Additionally, white tea has elevated levels of theobromine, a substance that can improve circulation. To produce white tea, basic tea leaves are picked when they are very young, so white tea contains considerably less fluoride than black or green tea and much higher levels of theanine, which is known for its relaxing qualities. Research indicates that white tea has an amount of caffeine comparable to that of either black or green tea.
The passage implies all of the following EXCEPT:
(A) Because it is more delicate and rarer than black or green tea, white tea may be more costly than the other forms of tea.
(B) White tea is usually derived from the same leaves as black or green tea, but it is picked when it is younger, and the leaves are not processed or fermented.
(C) Research suggests that white tea has extra benefits that black or green tea do not always have.
(D) Fluoride is a necessary ingredient for tea, so most white tea producers add fluoride to the tea that they sell.
(E) The increased levels of theanine in white tea have the potential to counter the effects of caffeine more than in black or green tea.
OFFICIAL EXPLANATION
Overview: Question presents the student with information about white tea, noting specifically its similarities and differences to black and green tea. The author of the passage mentions that white tea is usually more “delicate” and “rarer” than black or green tea and that it contains higher levels of certain chemicals—many of which have very positive health effects. The question then asks the student to identify the answer choice that is not implied in the passage. This is a fairly difficult question to answer correctly, because the student has to look closely to know for sure that the incorrect answers actually are implied. The correct answer, in this case, will be the answer choice that has absolutely no substance in the passage and cannot be inferred from any statements made.
The Correct Answer:D The author of the passage mentions that white tea “contains considerably less fluoride than black or green tea.” The author makes no comment anywhere else in the paragraph to indicate whether or not fluoride is a typical ingredient in tea, so it is impossible to determine from this alone if the lack of fluoride is viewed as a positive or a negative quality. Because the author of the passage is silent, answer choice (D) cannot be clearly inferred, so it is correct.
The Incorrect Answers:A The author of the passage claims that white tea is “more delicate and rarer than black or green tea and has fewer producers.” From this, the student may deduce that a delicate, rare product with few producers may be more costly than its counterparts—as the answer choice claims. Answer choice (A), therefore, may be inferred, so it is incorrect.
B In the middle of the passage, the student will read the following: “To produce white tea, basic tea leaves are picked when they are very young.” This implies strongly that white tea is just a product of regular tea leaves being picked at a young age and is not necessarily a different variety than black or green tea. Answer choice (B) may be inferred, so it is incorrect.
C The passage notes several times the differences between white tea and black or green tea, in each case identifying the chemicals contained in white tea that may improve health. From this, the student may deduce that there are possible health benefits to drinking white tea, benefits that are not obtained from drinking black or green tea. The passage implies answer choice (C), so it is incorrect.
E Answer choice (E) might be the most difficult answer choice to eliminate, because it requires that the student read the passage very carefully and infer very closely. Toward the end of the passage, the author claims that white tea has “much higher levels of theanine, which is known for its relaxing qualities.” In the final sentence, the author concludes with the statement that white tea has “an amount of caffeine comparable to that of either black or green tea.” If white tea has the same amount of caffeine as black or green tea but higher levels of a chemical that is known to induce relaxation, it may be inferred that the theanine in white tea has the potential to counter the effects of caffeine. Answer choice (E), then, is implied, so it is incorrect
