Deriving Conclusions From Passages Questions and Answers

Answer: A

Correct answer: Definitely true

This is stated almost directly. The passage says India needs higher investment in the port sector, that its ports still lag far behind international ports in container traffic, and that they need to be continually benchmarked against the best ports worldwide. Taken together those are precisely the claim that considerable development is needed to match the best, so the inference follows without any assumption of its own.

Answer: D

It is mentioned in the passage that there is a need to engage in policy efforts so as to attain prices per container 'of port services which are the lowest in the world. This indicates that at present these service charges are not the lowest.

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: B

Correct answer: Data inadequate

The passage says very few laboratory tests are available for the diagnosis of rabies in India. It says nothing whatever about the position in western countries. A shortage in one country tells you nothing about provision in another - it does not even establish a contrast, since the passage never draws one - so the statement can be neither confirmed nor denied from what is given.

Answer: D

Correct answer: Data inadequate

The passage explains that the virus is present in the saliva of an infected animal, but it never discusses screening healthy dogs, nor the periodic testing of any animal. It gives precautionary measures for the bite victim - washing the wound, then cetavlon, tincture of iodine or spirit - not a programme of surveillance. The recommendation in the statement is simply not addressed.

Answer: A

Correct answer: Definitely false

The passage supplies the figure that settles this: if not treated, about half of such cases develop rabies. Half is not all, so a bite cannot be said definitely to result in the disease - and if the wound is treated promptly the proportion is lower still. The word ‘definitely’ is what makes the statement false; without it the claim would have been a reasonable one.
