Question

Some scientists advocate for the use of alternative fuels, such as biofuels, in vehicles. These fuels are often made from natural materials such as corn or algae. Although many of these biofuels are still in the developmental stage, scientists believe they will be able to perform similarly to fossil fuels. Some biofuels, such as ethanol, are already in use and are able to propel certain vehicle types. One of the main reasons scientists support biofuel research is that these fuels are easier to replenish than fossil fuels. The process of fossilization of animals and plants takes longer, while biofuels can be made by faster-growing organisms, such as corn or algae.

Which piece of evidence from the passage supports the hypothesis that biofuel emissions are renewable and fossil fuels are not?

Answers

'Some biofuels, such as ethanol, are already in use and are able to propel certain vehicles types.'
correct

'The process of fossilization of animals and plants takes longer, while biofuels can be made by faster-growing organisms, such as corn or algae.'
'These fuels are often made from natural materials such as corn or algae.'
'Although many of these biofuels are still in the developmental stage, scientists believe they will be axle to perform similarly to fossil fuels.’

Explanation

The correct answer is:

"The process of fossilization of animals and plants takes longer, while biofuels can be made by faster-growing organisms, such as corn or algae."

This statement directly compares the time scales of fossil fuel formation and biofuel production. It highlights that fossil fuels require a lengthy fossilization process, implying their non-renewable nature. In contrast, biofuels are derived from faster-growing organisms, indicating a renewable source. This comparison emphasizes the key difference in renewability between the two fuel types, supporting the hypothesis that biofuel emissions are renewable while fossil fuels are not.
