Which of the following was developed as a result of the inflation that took place during the 1960s and 1970s? a. stagflation c. automatic stabilizers b. passive fiscal programs d. monetarist point of view

A. Stagflation

Explaining: Stagflation was developed during the 1960s and 1970s. In economics, stagflation, a portmanteau of stagnation and inflation, is a situation in which the inflation rate is high, the economic growth rate slows, and unemployment remains steadily high. It raises a dilemma for economic policy, since actions designed to lower inflation may exacerbate unemployment, and vice versa. The term is generally attributed to Iain Macleod, a British Conservative Party politician who became Chancellor of the Exchequer in 1970; Macleod coined the phrase in a speech to Parliament in 1965.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'

the answer is account d
