More questions
Correct Answer: Only assumption II is implicit
Explanation:
Clearly, the advertisement does not mention the word 'only' i.e. other air-conditioners may also have wide variations. So, I is not implicit. Also, the advertisement is given so that the people know about that which they demand. So, II is implicit.
Correct Answer: toxic insecticides such as DDT have not been banned throughout the world.
Explanation:
The support for this choice is in the second sentence, which states that in some countries, toxic insecticides are still legal. Choice b is incorrect because even though polar regions are mentioned in the paragraph, there is no support for the idea that warmer regions are not just as affected. There is no support for choice c. Choice d can be ruled out because there is nothing to indicate that DDT and toxaphene are the most toxic. Choice e is illogical.
Correct Answer: adults are not heeding the warnings about the dangers of sun exposure seriously enough.
Explanation:
The last sentence gives direct support for this response. Although children might be better protected from the sun than adults, the paragraph does not specifically cite statistics about children, so we can't know for sure, ruling out choice a. There is no evidence provided in the paragraph to support choices b and d. Choice e is incorrect since the last sentence tells us that warnings about the sun's dangers are frequent.
Correct Answer: arid
Explanation:
A desert is an arid tract of land. Not all deserts are flat (choice d). Not all deserts have cacti or oases (choices a and c).
Correct Answer: Carter
Explanation:
Baxter should be assigned to study with Carter. Baxter cannot be assigned with Adam, because they have already been together for seven class periods. If Baxter is assigned to work with Dennis, that would leave Adam with Carter, but Carter does not want to work with Adam.
Correct Answer: Only I and II follow
Explanation:
First of all, company A should inspect the rejected valves to ensure if they are really sub-standard. If yes, it should scrutinise its working thoroughly and remove its lackenings, be it in the quality of raw material or craftsmanship. So, both I and II follow. III seems to be a far-off action which can be implemented only after the first two steps are put into practice. Thus, III does not follow,
Correct Answer: patricrin
Explanation:
In this language, the adjective follows the noun. From
dionot and
blyonot, you can determine that 'onot' means oak. From
blyonot and
blycrin, you can determine that
bly means leaf. Therefore,
crin means maple. Because the adjective maple comes after the noun,
patricrin is the only possible choice.
Correct Answer: Either I or II follows
Explanation:
Clearly, either I or II could be the reason for the situation expressed in the statement.
Correct Answer: Only conclusion II follows
Explanation:
The phrase 'only book' in the statement makes II implicit. However, nothing about the state of poverty before 1950 can be deduced from the statement. So, I does not follow.
Correct Answer: Neither I nor II follows
Explanation:
Since the company has been working in this area for three decades, it must have the necessary expertise and infrastructure required in this field. So, I does not follow. However, the qualities that have made the Company X successful in this field have not been mentioned. So, II also does not follow.
