Question

Recently, ornithologists surveying the bird population of the remote forests of the Kamchatka Peninsula reported sighting a banded nuthatch. Most ornithologists consider the banded nuthatch to have become extinct in the 19th century, since the last verified sighting of a banded nuthatch was in 1895. It is therefore most reasonable to conclude that the ornithologists who claimed to have spotted the banded nuthatch recently were mistaken.
Which of the following statements, if true, most seriously weakens the argument above?A) Although experienced, the ornithologists participating in the survey had never before visited the forests of the Kamchatka PeninsulaB) The Banded Nuthatch was always a rare bird, and the last verified sighting prior to 1895 was in 1815C) It is rare that a species thought to be extinct is found to be still in existenceD) The Lesser Nuthatch, a bird known to be widespread in the forests of the Kamchatka Peninsula, is very similar to the Banded Nuthatch in appearanceE) The ornithologists surveying the birds of the Kamchatka Peninsula are among the most respected and highly regarded in their field

Answer 1

Answer:

D) The Lesser Nuthatch, a bird known to be widespread in the forests of the Kamchatka Peninsula, is very similar to the Banded Nuthatch in appearance

Explanation:

All over the world, plants and animals do tend to have similarity among same group. This is part of the reasons why some animals with similar resemblances tends to be classified under same class under the classification of animals. Despite the fact that there is an established point of the nuthatch bird being extinct in the 19th century, the claim that the ornithologist being wrong in sighting the nuthatch could be weaked if the birds happens to be the Lesser Nuthatch.

This could be the fact that Lesser Nuthatch birds is a sub-class in the Nuthatch bird family just as rice and millet being in same grain family under the plants classification (but different under class).
