GENERAL KNOWLEDGE

Detailed explanation-1: -ostrich, (Struthio camelus), large flightless bird found only in open country in Africa. The largest living bird, an adult male may be 2.75 metres (about 9 feet) tall-almost half of its height is neck-and weigh more than 150 kg (330 pounds); the female is somewhat smaller.

Detailed explanation-2: -The flightless ostrich is the world’s largest bird. They roam African savanna and desert lands and get most of their water from the plants they eat.

Detailed explanation-3: -The word ‘ostrich’ starts with a vowel and hence, in most cases the blank will be filled with ‘an’. But, in this case, we are taking in the superlative form about the entire species of ostriches, and hence, the article used should be ‘the’.
