• Question 2 of 10 2. Question 1 points What best characterizes the concept of “entrenched inflation”? (a) A temporary increase in prices due to seasonal fluctuations in demand. (b) Persistent and sustained rise in the general price level of goods and services over a prolonged period. (c) An abrupt and short-lived spike in inflation caused by external shocks to the economy. (d) Fluctuations in prices resulting from changes in consumer preferences and tastes. Correct Ans: (b) Explanation: Context: In 2023, while world food prices experienced a significant decline from their 2022 highs, India saw persistently high food inflation, reaching 9.5% in December 2023. This contrasts sharply with global deflation of -10.1% during the same period. If inflation were entrenched, it would mean that prices would not come back down, and that the new prices we see in the market would be a more permanent fixture in the economic life of citizens. Entrenched inflation tends to stick around even after the immediate problems that spurred it on have resolved.

• Question 9 of 10 9. Question 1 points How does ethylene gas affect the ripening of fruits and vegetables? (a) It inhibits the production of enzymes involved in ripening. (b) It accelerates the breakdown of carbohydrates, leading to ripening. (c) It increases the acidity of fruits, enhancing their flavor profile. (d) It reduces the water content in fruits, resulting in faster ripening.
