Deriving Conclusions From Passages Questions and Answers

Answer: C

Correct answer: Definitely true

The passage says that not much has so far been done in this field, while the survey shows a vast potential for developing wind as an alternative source of energy. Little done so far together with large potential still to be developed is precisely what makes a field new and emerging, so the inference restates what the passage asserts.

Answer: D

Correct answer: Definitely true

The passage calls wind an inexhaustible source of energy which an aerogenerator can convert into electricity, and describes a vast potential for developing it as an alternative source of energy. To be an alternative to the exhaustible sources is to be capable of taking their place, so the statement follows from the passage’s own description rather than from anything added to it.

Answer: B

Correct answer: Probably true

The survey’s results are reported for U.P. and its recommendations are about U.P. hill areas, which makes the state government the natural sponsor. But the passage never names who commissioned it, and a national agency surveying wind resources across the country would produce exactly the same U.P. findings. The inference is likely but not established.

Answer: C

Correct answer: Probably false

The wording of the passage tells against this. It says that in the U.P. hills alone as many as 58 sites have been identified - and ‘alone’ only makes sense if other areas were examined too, with the hills singled out as the richest. The statement’s ‘only’ therefore runs against the passage’s implication, though the passage never states the wider scope outright.

Answer: C

Correct answer: Data inadequate

The passage says Armstrong became the first man to set foot on the moon in July 1969. Being the first on the moon is not the same as being the first in space, and the passage says nothing about who first went into space. Without that information the statement cannot be judged either way from the passage alone - whatever you may know from elsewhere, the test is what the passage supports.

Answer: B

Correct answer: Probably true

The passage says space probes carry a large variety of the latest scientific instruments on board and that they have sent back close-up pictures and other data. Craft that must operate unattended and transmit data across such distances would need computers, and the reference to the latest instruments points the same way - but the passage never actually says the word, so this is a reasonable inference rather than a stated fact.

Answer: D

Correct answer: Definitely false

The passage contradicts this directly. Space probes are described as returning pictures and data about planets and other bodies in outer space, which is far beyond the earth’s atmosphere. The upper atmosphere belongs to a different sentence, about the original purpose of artificial satellites, and the word ‘only’ in the statement makes the clash unmistakable.

Answer: A

It is mentioned in the passage that the space probes have provided pictures and certain data of the outer space and the heavenly bodies. Thus, they have helped us increase our knowledge of outer space and the bodies in it.

Answer: A

Correct answer: Definitely true

The passage says Neil Armstrong became the first man to set foot on the moon on 20 July 1969. A man setting foot on the moon is exactly what exploration of the moon by man means, so the inference follows from the stated fact with nothing added. Note that ‘first man’ also implies others followed, but even the one landing is enough to make the statement true.

Answer: C

Correct answer: Data inadequate

The passage says Indian ports should be benchmarked against the best ports worldwide, but it never says where those ports are. Nothing in it points to the United States or to any other country. The statement is therefore neither supported nor contradicted - it is simply outside what the passage tells us, which is what makes it a data inadequate case rather than a false one.
