Question 1 of 5
1. Question
1 pointsConsider the following statements.
1. The expansion created by the “Big Bang” continues even to the present day.
2. After the Big Bang, the Universe became highly opaque and temperatures started rising till the atmosphere was formed.
Which of the above statements is/are incorrect?Correct
Only 2 is incorrect.
The Big Bang Theory considers the following stages in the development of the universe.
(i) In the beginning, all matter forming the universe existed in one place in the form of a “tiny ball” (singular atom) with an unimaginably small volume, infinite temperature and infinite density.
(ii) At the Big Bang the “tiny ball” exploded violently. This led to a huge expansion. It is now generally accepted that the event of big bang took place 13.7 billion years before the present. The expansion continues even to the present day. As it grew, some energy was converted into matter. There was particularly rapid expansion within fractions of a second after the bang. Thereafter, the expansion has slowed down. Within first three minutes from the Big Bang event, the first atom began to form.
(iii) Within 300,000 years from the Big Bang, temperature dropped to 4,500K (Kelvin) and gave rise to atomic matter. The universe became transparent.Incorrect

Question 2 of 5
2. Question
1 pointsConsider the following statements regarding Temperate Rainforests.
1. Temperate rainforests are found mostly in coastal, mountainous areas.
2. Cooler temperatures and a more stable climate slow down decomposition, allowing more material to accumulate.
3. Temperate rainforests are the most biologically diverse terrestrial ecosystems in the world.
Which of the above statements is/are correct?Correct
1 and 2 are correct.
Temperate rainforests are located in the mid-latitudes, where temperatures are much more mild than the tropics.
Temperate rainforests are found mostly in coastal, mountainous areas. Rainfall in these forests is produced by warm, moist air coming in from the coast and being trapped by nearby mountains.
Cooler temperatures and a more stable climate slow down decomposition, allowing more material to accumulate. This productivity allows many plant species to grow for incredibly long periods of time.
Tropical rainforests are the most biologically diverse terrestrial ecosystems in the world.Incorrect

1. In India, oilseeds are largely grown under rainfed conditions.
2. Soybean and groundnut contributes to more than 80% of total oilseeds production in India.
3. Madhya Pradesh, Maharashtra and Rajasthan are the major Soybean growing states.
Which of the above statements is/are correct?Correct
1 and 3 are correct.
Soybean (34%), groundnut (27%), rapeseed & mustard (27%) contributes to more than 88% of total oilseeds production and >80% of vegetable oil with major share of mustard (35%), soybean (23%) and groundnut (25%).
Andhra Pradesh (groundnut) & Gujarat (groundnut), Haryana (Mustard), Karnataka (G.nut), M.P(Soybean), Maharashtra (Soybean), Rajasthan (Mustard & Soybean), Tamil Nadu (G. nut), U.P(Mustard), West Bengal (Mustard) contributing more than 95% of total oilseed production in the country.
Majority of the oilseeds are cultivated under rainfed ecosystem (70%).Incorrect
