Passage: Humans and monkeys are mammals, in the animal family known as primates. These are not the only animals whose numerical capacities rely on ratio. The same seems to apply to some amphibians. Psychologist  Claudia Uller’s team tempted salamanders with two sets of fruit flies held in clear tubes. In a series of trials, the researchers noted which tube the salamanders scampered towards, reasoning that if they could recognize the number, they would head for the larger number. The salamanders successfully discriminated between tubes containing 8 and 16 flies respectively, but not between 3 and 4. 4 and 6, or 8 and 12. So it seems that for the salamanders to discriminate between two numbers, the larger must be at least twice as big as the smaller. However, they could differentiate between 2 and 3 flies and between 1 and 2 flies, suggesting they recognize small numbers differently from larger numbers.

Q.1. Primates are the only animals whose numerical capacities rely on ratio.
Q.2. Salamanders were tempted by two sets of fruit flies by Claudia Uller and the researchers.
Q.3. It was very difficult for Claudia Uller’s team to recognize the scampered salamanders in the tube.
Q.4. Salamanders could easily discriminate between the tubes containing 8 and 12 flies.
Q.5. The researchers gave a final reason that the salamanders could discriminate between two numbers in which the larger number must be twice as big as the smaller number.

Solution of 1:

Primates are the only animals whose numerical capacities rely on ratio – NO.
we know from the passage that the human and monkeys are mammals who are also known as primates in the animal family. These are not the only animals whose numerical capacities rely on ratio, but it also applies to some amphibians. So, the answer is NO.

Solution of 2:

Salamanders were tempted by two sets of fruit flies by Claudia Uller and the researchers. – YES.
it is mentioned in the passage that psychologist Claudia Uller’s team tempted salamanders with two sets of fruit flies in clear tubes. So, the answer is YES.

Solution of 3:

It was very difficult for Claudia Uller’s team to recognize the scampered salamanders in the tube – NOT GIVEN.
it is not mentioned anywhere in the passage that Claudia and her team of researchers found it difficult to recognize the scampered salamanders in the tube. So, the answer is NOT GIVEN.

Solution of 4:

Salamanders could easily discriminate between the tubes containing 8 and 12 flies – NO.
it is clearly given in the passage that the salamanders were successful in discriminating between the tubes which contained 8 and 16 files and not 8 & 12 flies. So, the answer is NO.

Solution of 5:

The researchers gave a final reason that the salamanders could discriminate between two numbers in which the larger number must be twice as big as the smaller number – YES.
we understand that the salamanders were able to discriminate between two numbers from the passage. The larger must be at least twice as big as the smaller. So, the answer is YES.
