As part of the American Recovery and Reinvestment Act, $7 million was earmarked to build a bridge over a railroad crossing so that 168 Nebraska town residents wouldn't have to wait for the trains to pass. Which of the following best explains why this proposal was passed? A) The benefits were highly diffused while the costs were very concentrated.
B) The costs were highly diffused while the benefits were very concentrated.
C) The costs were external while the benefits were internal.
D) The total benefit to the bridge was greater than the total cost

B) The costs were highly diffused while the benefits were very concentrated

Explanation: The American Recovery and Reinvestment act was enacted by congress and passed into law in 2009. The act which was aimed at alleviating the burden and promoting economic growth after the 2008 recession. It was meant to serve as a palliative or stimulus to aid economic recovery. The $7 million proposal earmarked to erect a bridge over the railway crossing was passed into law due to the fact that the benefits, relief and succor which the bridge provides to the over 168 Nebraskans coupled with the subsidized or diffused cost of putting the bridge in place were decisive factors towards acceptance of the proposal.

answer: yo mama

explanation: yo mama

ans.

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.'
