QUES: Though the true dimensions of species diversity remain uncertain, estimates range from 2.67.8 million species with a mean of 5.5 million. This probably represents less than 20% of all species on Earth[citation needed], and with only about 20,000 new species of all organisms being described each year, most species likely will remain undescribed for many years unless species descriptions increase in rate. About 850,0001,000,000 of all described species are insects. Of the 24 orders of insects, four dominate in terms of numbers of described species, with at least 3 million species included in Coleoptera, Diptera, Hymenoptera and Lepidoptera. A recent study estimated the number of beetles at 0.92.1 million with a mean of 1.5 million.

How many insect species are estimated to exist?
What is the answer?
ANS: 2.67.8 million species
QUES: In 200607, researchers from the Wildlife Conservation Society studied gorillas in heavily forested regions centered on the Ouesso district of the Sangha Region. They suggest a population on the order of 125,000 Western Lowland Gorillas, whose isolation from humans has been largely preserved by inhospitable swamps.

What was responsible for maintaining the separation between the gorillas and humans?
What is the answer?
ANS: inhospitable swamps
QUES: In 1927, the Kuomintang (KMT; Nationalist Party) under Generalissimo Chiang Kai-shek again established Nanjing as the capital of the Republic of China, and this became internationally recognized once KMT forces took Beijing in 1928. The following decade is known as the Nanking decade.
