GED Test Science Question 1 of 38

Some scientists advocate for the use of alternative fuel, 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 vehicles 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?

• “Some biofuels, such as ethanol, are already in use and are able to propel certain vehicles types.”
• “The process of fossilization of animals and plants takes longer, while biofuels can be made by faster-growing organisms, 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.”
• “These fuels are often made from natural materials such as corn or algae.”

The answer that supports the hypothesis that biofuel emissions are renewable and fossil fuels are not 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.”
