Despite long-standing scientific debates about the misuse of fossil fuels, there is now a consensus among most scientists that human activities are hastening the depletion of these resources. While estimates vary, many experts in the field believe that Earth's fossil fuel reserves will be exhausted by the next century. Such a scenario would lead to a global shutdown of all industries and equipment dependent on fossil fuels, significantly disrupting habitats and the resources necessary for the survival of billions of people.
Which of the following assumptions supports the argument's conclusion?
A. New technological developments in the next century will not create alternatives to fossil fuels.
B. Individuals will not increase their awareness of steps to reduce fossil fuel consumption.
C. The global shutdown of industries and equipment that use fossil fuels will affect all regions of Earth equally.
D. Some experts predict that fossil fuels will be depleted even sooner than projected.
E. Human activity is the sole cause of fossil fuel depletion.
Which of the following assumptions supports the argument's conclusion?

Official Solution:
Despite long-standing scientific debates about the misuse of fossil fuels, there is now a consensus among most scientists that human activities are hastening the depletion of these resources. While estimates vary, many experts in the field believe that Earth's fossil fuel reserves will be exhausted by the next century. Such a scenario would lead to a global shutdown of all industries and equipment dependent on fossil fuels, significantly disrupting habitats and the resources necessary for the survival of billions of people.
Which of the following assumptions supports the argument's conclusion?
A. New technological developments in the next century will not create alternatives to fossil fuels.
B. Individuals will not increase their awareness of steps to reduce fossil fuel consumption.
C. The global shutdown of industries and equipment that use fossil fuels will affect all regions of Earth equally.
D. Some experts predict that fossil fuels will be depleted even sooner than projected.
E. Human activity is the sole cause of fossil fuel depletion.
The argument concludes that depletion of fossil fuels caused by human activity will shut down of all the industries and equipments that use fossil fuels, disturbing habitat and resources for survival for billions. Any assumption in support of this conclusion would have to corroborate that these events will definitively take place..
A. CORRECT. If new technological developments in the next century allow people to come up with an alternative for fossil fuels, then industries and equipments that use fossil fuels will not shut down. Thus, a necessary assumption is that these technologies will not be developed.
B. A simple awareness of the steps to reduce the consumption of fossil fuels in no way undermines the argument’s conclusion, as this answer choice does not describe any action being taken by individuals.
C. The argument never suggests that all parts of the Earth will be similarly affected; this choice is outside of the scope of our argument. The impact does not have to be uniform for the impact to happen and to significantly disrupt human lives.
D. This might be true, but it is not an assumption on which the conclusion rests. Instead, this answer choice is simply an inference that might be drawn from the premises. This a good example of a choice which can be true based on the stimulus but not actually a valid assumption.
E. The idea that human activity is the sole cause of fossil fuel depletion is neither suggested nor assumed by the argument. In addition, the wording "sole cause" is too extreme.

I have doubts about the correctness of the answer. I was choosing between A and B but chose B because I decided that A would not always work. As with any assumption questions we can use negation technique here, right? If we negate answer A, we will get that "New technological developments in the next century WILL create a substitute for fossil fuels". This will hurt the conclusion of the argument, but only in case the substitute will be created somewhere in the beginning of the next century. What if they are created in 2190? Then, for 90 years the world will have to survive without fossil fuels and without any alternatives. In this case, "global shut down of all the industries and equipments that use fossil fuels, disturbing habitat and resources for survival for billions of people" is likely.
Answer B is also flawed due to the reasons decribed in OA, but I think answer A is hardly better.. Please let me know what do you think? Bunuel
Thanks in advance!
