Officer English set-1

 


Read the following passage and tick the right options:

Bats are not, bloodthirsty monsters as portrayed in vampire films. These winged mammals groom themselves carefully like cats and only rarely carry rabies. Of the hundreds of species of bats, only three rely on blood meals. In fact, the majority eats fruit, insects, spiders, or small animals; same species gather nectar and pollen from flowers. The environmental benefits of bats are myriad. They consume an enormous number of pests, pollinate many varieties of plant life, and help reforest huge tracts of barren land by exerting millions of undigested seeds.

Bats also have served as models for sophisticated navigation in naval and airplane technology. Living models for radar and sonar, almost all bats use echolocation to navigate, especially at night. As they fly, they a series of high – pitched squeaks at the rate of about fifty per minute. As these signals bounce off objects in their path, an echo is detected by the bats’ sensitive ears that inform them of the direction, distance, and nature of obstacles so that they can undertake corrective or evasive action. Echoes are used by bats but not because of physical limitations or impairments, for bats are not blind as widely assumed. In fact, all species of bats can see, probably about as well as human beings. Another myth, about bats being aggressive, intentionally entangling themselves in the hair of human beings, is also totally unfounded. It has been shown in studies not only that bats are timid, but also that they will assiduously avoid contact with large creatures than themselves if possible.
