SSC MTS 2022 Previous Year GK Questions with Answers

The correct answer is A, Night blindness. Vitamin A, chemically retinol, is needed to make rhodopsin, the light-sensitive pigment in the rod cells of the retina that lets us see in dim light. When the vitamin is short, the eye cannot adjust to darkness, and the person cannot see properly at night or in poor light; this is night blindness (nyctalopia). If the deficiency continues, the eye becomes dry and the cornea is damaged, a condition called xerophthalmia, which can end in total blindness. Vitamin A is fat-soluble and comes from carrots, papaya, mango, green leafy vegetables, milk, eggs and fish liver oil. B is wrong because scurvy, with bleeding gums, is caused by lack of vitamin C. C is wrong because marasmus is caused by a severe shortage of both calories and protein in young children. D is wrong because kwashiorkor is a protein deficiency disease marked by a swollen belly. Exam tip: vitamin A night blindness, C scurvy, D rickets, K bleeding; marasmus and kwashiorkor are protein-energy problems, not vitamin diseases.

The correct answer is B, Base year. Real GDP measures the value of all final goods and services produced in a year at the prices of one fixed earlier year, called the base year, so that the effect of rising prices is removed and true growth can be seen. Nominal GDP uses the current year's prices. The ratio of nominal GDP to real GDP, multiplied by 100, is the GDP deflator, a measure of inflation. The base year is chosen by the government's statistics office and is revised from time to time so that it reflects the present structure of the economy. A is wrong because the fiscal year is simply the twelve months over which accounts are kept, April to March in India. C is wrong because financial year is another name for the same accounting period, not a price reference. D is wrong because 'common year' means a calendar year of 365 days, a term from the calendar, not economics. Exam tip: real GDP = base-year prices, nominal GDP = current prices; GDP deflator = nominal divided by real, times 100.
