Question

read the paragraph from the hot zone and the summary that follows it.

once the cells in a biological machine stop working, it can never be started again. it goes into a cascade of decay, falling toward disorder and randomness. except in the case of viruses. they can turn off and go dead. then, if they come in contact with a living system, they switch on and multiply. the only thing that \lived\ inside this monkey was the unknown agent, and it was dead, for the time being. it was not multiplying or doing anything, since the monkeys cells were dead. but if the agent touched living cells, nancys cells, it would come alive and begin to amplify itself. in theory, it could amplify itself around the world in the human species.

summary of central idea: it is petrifying that even if viruses are dead, they have the potential to \come alive.\

which changes should be made to improve this summary of the paragraphs central idea? select two options.

remove the phrase \it is petrifying\ because it expresses a personal feeling.
include the detail that there was a dead virus living inside the monkey.
remove the detail that viruses can come alive even if they are dead.
add the phrase \and spread throughout the human species\ to the end of the statement to more fully express the central idea.
add a personal opinion about what may happen if the virus does \come alive.\

Analyze the summary's objectivity

An objective summary must remain completely factual and free of personal opinions or emotional language. The current summary begins with "It is petrifying," which is a subjective emotional reaction rather than an objective detail from the text. Therefore, removing this phrase improves the summary's objectivity.

Evaluate the central idea details

The paragraph discusses how viruses can "turn off and go dead" and then "come alive" and multiply when touching living cells, potentially amplifying "around the world in the human species." The current summary states: "even if viruses are dead, they have the potential to 'come alive'." Adding the detail about spreading throughout the human species captures the full scope of the threat described in the text, which is a key part of the central idea.

Assess the remaining options

• Including "a dead virus living inside the monkey" is a minor supporting detail, not a central idea improvement.
• Removing the detail that viruses can come alive would remove the actual central idea of the passage.
• Adding a personal opinion violates the fundamental rule of objective summarizing.
