The logic problems in this set present you with three true statements: Fact 1, Fact 2 and Fact 3. Then you are given three more statements (labelled I, II, III), and you must determine which of these, if any, is also a fact. One or two of the statements could be true; or none of the statements could be true. Fact 1: All chickens are birds. Fact 2: Some chickens are hens. Fact 3: Female birds lay eggs. If the first three statements are facts, which of the following statement/(s) must also be a fact? I. All birds lay eggs. II. Hens are birds. III. Some chickens are not hens. Choose the correct answer from the options given below: 
Consider the following statements and choose the correct answer:
1. The biogeographical realms are regions made up of whole continents, or of large parts of a continent, separated by major geographic barriers and characterized by the presence of certain unique animals and plants
2. In each biome the kind of climax vegetation is uniform - grasses, conifers, deciduous trees but the particular species of plant may vary in different parts of the biome
3. There is usually a sharp line of demarcation between adjacent biomes
4. The definition of biome includes not only the actual climax community of a region but also the several intermediate communities that precede the climax community
In the question, two statements are given, followed by three conclusions, I, II and III. You have to consider the statements to be true even if they seem to be at variance from commonly known facts. You have to decide which of the given conclusions, if any, follow(s) from the given statements. Statement 1: All bamboo are tall. Statement 2: All tall are grass. Conclusion I: Some grass are bamboo. Conclusion II: Some tall are bamboo. Conclusion III: Some grass are tall.
Fact 1: All chickens are birds.
Fact 2: Some chickens are hens.
Fact 3: Female birds lay eggs.

Read the following passage carefully and choose the most appropriate answer to the question out of the four alternatives.
Riparian vegetation [the green band of vegetation along a watercourse] can help stabilize stream banks; filter sediment from surface runoff; and provide wildlife habitat, livestock forage,and scenic value. Well-developed vegetation also allows bank soils to absorb extra water during spring runoff, releasing it later during drier months, thus improving late-summer stream flows. In many parts of the arid West, trees and shrubs are found only in riparian areas. Woody plants are very important as winter cover for many wildlife species, including upland game birds such as pheasants and turkeys. Often this winter cover is the greatest single factor limiting game bird populations. Woody vegetation also provides hiding cover and browse for many other species of birds and mammals, both game and nongame. Dead trees ("snags") are an integral part of streamside habitats and should be left standing whenever possible. Woodpeckers, nuthatches, brown creepers, and other birds eat the insects that decompose the wood. These insects usually pose no threat to nearby living trees. Occasionally a disease organism or misuse of pesticides will weaken or kill a stand of trees. If several trees in a small area begin to die, contact your local extension agent immediately . How dependent are plants and animals on each other?

P :Though they are functionally similar to the humming birds of the New World, they are totally unrelated.
Q :They do eat insects too.
R :They are also some of the most brilliantly coloured birds.
S :sun birds feed on nectar mostly and helped in pollination.
S6:Our common sun birds are the purple sun bird, the glossy black species and purple rumped sun bird, the yellow and maroon species.
