Question : Comprehension: Wildlife and nature have largely been associated with humans for numerous emotional and social reasons. A simple stroll around the park amidst some birds provides a fresh breath of life and charges our batteries. Apart from a bird feeder in the backyard, we can also take up other active pastimes, such as hiking, hunting, canoeing, or wildlife photography, to relieve our parched nerves. Since prehistoric times, animals have been highly useful to us in providing food, clothing, and a source of income. Studies indicate that woodpeckers are capable of destroying 90% of codling moth larvae residing under the bark of trees. This shows the significance of wildlife and wildlife habitat for preserving genetic diversity. Hence, places, where agriculture, forests, and fisheries depend on crops or stocks, can ensure that such living resources are enough to withstand the ever-increasing list of threats. Further, in medicine, the development of new drugs and treatments is largely dependent on wildlife and wildlife habitat. Interestingly, most pharmaceutical products are a result of discovering or developing wildlife species, not discoveries made through traditional chemistry principles. Today, most medicinal remedies contain at least one ingredient derived from a wild plant or animal. Biodiversity is the variety of living beings within an ecosystem or on our planet. It is a measurement of the health of ecosystems. Biodiversity also plays a part in the function of climate. In terrestrial habitats, tropical areas are rich in species, whereas polar areas support fewer species. The conservation of biodiversity is inevitable for the survival of humans. Based on the passage above, choose the correct option for the following questions:
Question: Biodiversity is _____.
Option 1: associated with humans for numerous reasons
Option 2: rich in species
Option 3: inevitable for the survival of men
Option 4: a different variety of living beings within an ecosystem
Correct Answer: a different variety of living beings within an ecosystem
Solution : The fourth option is correct.
Explanation:
According to the given passage, biodiversity refers to the variety of living organisms within a particular ecosystem or on our planet as a whole. It encompasses different species of plants,

Question : Direction: A word is represented by only one set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabets as in the two matrices, given below. The columns and rows of Matrix (I) are numbered from 0 to 4 and that of Matrix (II) are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, e.g. 'F' can be represented by 30, 23, etc., and 'N' can be represented by 97, 89, etc. Similarly, you have to identify the set for the given word.

Question : Directions: Six books Hindi, Biology, Mathematics, Economics, Physics, and Chemistry are placed in two racks facing each other with three books in each rack. Hindi and Chemistry are in the same rack but are not neighbours. Biology is placed exactly opposite to Economics. Biology is just left of Hindi facing the South direction. Physics is exactly opposite to Chemistry. Which of the following is placed exactly opposite to Hindi?
Option 1: Chemistry
Option 2: Economics
Option 3: Biology
Option 4: Mathematics
Correct Answer: Mathematics
Solution : 1. Biology is just left of Hindi facing the South direction. Hindi and Chemistry are in the same rack but are not neighbours. 2. Biology is placed exactly opposite to Economics. Physics is exactly opposite to Chemistry.
So, Mathematics is the opposite of Hindi. Hence,
