The following text is adapted from Edgar Allan Poe's 1843 short story "The Tell-Tale Heart." The narrator is describing their feelings towards an old man they live with. "The old man had never wronged me. He had never given me insult. For his gold I had no desire. I think it was his eye! Yes, it was this! One of his eyes resembled that of a vulture—a pale blue eye, with a film over it. Whenever it fell upon me, my blood ran cold; and so by degrees—very gradually—I made up my mind to take the life of the old man, and thus rid myself of the eye forever. This idea haunted me day and night. It was not the old man who vexed me, but his Evil Eye."

Text 1

Historians have long debated the primary cause of the fall of the Roman Empire. Traditional theories often focus on military overextension and invasions by barbarian tribes. Many argue that these external pressures were too great for the empire to withstand. Despite extensive research, historians have not reached a consensus on this issue, with some suggesting that internal factors played a more significant role.

Text 2

Historian Dr. Julia Martinez and her team have recently presented a different perspective on the fall of the Roman Empire. They argue that the empire's decline was not solely due to external military pressures. Instead, they point to economic instability, including inflation and a failing trade network, as crucial factors. According to Martinez's research, internal economic challenges weakened the empire, making it more susceptible to external threats. This view challenges the traditional emphasis on military factors alone.

Based on the texts, how would Dr. Martinez and her team (Text 2) most likely respond to the “traditional theories” discussed in Text 1?

A study on the energy efficiency of various types of light bulbs was conducted, comparing their power usage (in watts) and light output (in lumens). Researchers observed that while light bulbs vary in power consumption, their luminous efficacy (light output per unit of power) tends to be more consistent. Therefore, they suggested that two different types of bulbs with varied power usage could nonetheless produce a similar amount of light.

Which choice best describes data from the study that support the researchers' claim?

A study on the fuel efficiency of different car models was conducted, comparing their fuel consumption (in liters per 100 kilometers) and travel range (in kilometers per tank).

A research group led by Dr. Laura Chen studied the role of the protein MYC in the regeneration of liver cells in mice. They observed that normal liver cells have low levels of MYC protein. However, when liver cells were damaged, there was a significant increase in MYC protein levels. To further test its role, they genetically engineered mice to lack the MYC protein in their liver cells. Following liver damage, these modified mice showed a markedly slower rate of liver cell regeneration compared to normal mice. In normal mice, the liver cells quickly regenerated, restoring liver function. This pattern of liver regeneration in the presence and absence of the MYC protein in mice, which suggests that ______
