Consider the following pairs : Country — Animal found in its natural habitat 1. Brazil — Indri 2. Indonesia — Elk 3. Madagascar — Bonobo How many of the pairs given above are correctly matched?

  1. A.Only one
  2. B.Only two
  3. C.All three
  4. D.None

Correct answer

D. None

Explanation

The correct answer is D, None. All three animals have been placed in the wrong country: the indri lives in Madagascar, the elk in the northern forests of Eurasia and North America, and the bonobo in the Democratic Republic of the Congo.

The indri is the largest living lemur, a black-and-white primate famous for its loud song; like all lemurs it is found only in Madagascar, so pairing it with Brazil is wrong. The elk (moose in North America) is a large deer of cold, northern forests and does not occur naturally in tropical Indonesia. The bonobo, a great ape closely related to the chimpanzee, lives only in the rainforests south of the Congo River, not in Madagascar.

Pair 1 is wrong: Brazil has monkeys such as the golden lion tamarin, not lemurs.

Pair 2 is wrong: Indonesia is home to the orangutan and the Komodo dragon, not the elk.

Pair 3 is wrong: Madagascar is the land of lemurs, not of great apes like the bonobo.

So A, B and C are wrong.

Exam tip: lemurs (indri) = Madagascar; bonobo = DR Congo; orangutan = Borneo and Sumatra.

Consider the following statements :

I. Carbon dioxide (CO2) emissions in India are less than 0.5 t CO2/capita.
