D looks good, but I will choose B
my explanation -
in the text it is mentioned this "the distinction between solar energy and energy derived from fossil fuel is artificial" and "All of the energy these fossil fuels contain once resided in the sun "

B for me too...

(B) is a clear choice from the 1st line of the argument and the supporting structure after that

The passage is basically this:

Fossil fuels got their energy from the sun. Here's how fossil fuels got their energy from the sun. Therefore, when we use fossil fuels, we are using energy from the sun.

It must be B.

In broad thermodynamic terms, the distinction between solar energy and energy derived from fossil fuel is artificial.Fossil Fuel molecules represent the decayed reamins of plants.All of the energy these fossil fuels contain once resided in the sun and was , so to speak , trapped by plants here on Earth through the process of photosynthesis, whereupon it was housed,principally, within the carbohydrate molecules of which the plants were composed.The process of burning unleashes that energy , and when we run our lights ,factories , and automobiles by burning fossil fuels ........

Which of the following is the most logical completion of the passage above

A) We deplete our stores of an ever more precious resource .
B) We use energy that is , in fact,derived from the sun.
C) We spend the legacy left to us by our prehistoric ancestors .
D) We mimic the process of energy generation that exists in the sun .
E) We return to the sun that which originally resided there .


This was basically an inference question and when you read the premises carefully, we find that the correct answer is B.


According to me the answer is B. Also please give the OA as soon as possible so that we do not have to come back to the same question....
