Question 228·Hard·Rhetorical Synthesis
While researching a topic, a student has taken the following notes:
- The axolotl (Ambystoma mexicanum) is native to several high-altitude lakes near Mexico City.
- It is neotenic, meaning it retains larval traits—such as external gills—throughout its life.
- It can regenerate entire limbs, large sections of its spinal cord, and even parts of its brain.
- Because few vertebrates share this level of regenerative ability, biomedical researchers study the axolotl for clues that could inform human tissue repair.
The student wants to highlight how extraordinary the axolotl’s regenerative capacity is compared with that of other animals. Which choice most effectively uses relevant information from the notes to accomplish this goal?
For rhetorical synthesis questions, restate the goal in your own words (here: emphasize that the axolotl’s regeneration is unusually powerful compared with other animals). Then choose the option that uses only relevant notes and does the most to meet the goal—typically combining explicit comparison language (e.g., “few vertebrates”) with the strongest supporting details (spinal cord/brain regeneration).
Hints
Match the goal to the notes
The goal is about regeneration compared with other animals. Focus on the notes about regeneration and how rare it is.
Look for comparison language
Which option explicitly signals rarity (for example, “few vertebrates”) rather than just listing facts?
Use the strongest regeneration details
The most impressive details include regeneration of the spinal cord and brain, not just limbs.
Step-by-step Explanation
Identify the goal
The sentence must highlight that the axolotl’s regenerative ability is extraordinary compared with other animals, so you need comparison language plus strong regeneration details.
Pull the most relevant notes
The notes that directly support that goal are:
- It can regenerate limbs, large sections of the spinal cord, and parts of the brain.
- Few vertebrates share this level of regenerative ability.
Check each option against the goal
Prefer an option that includes both (1) a rarity/comparison claim (like “few vertebrates”) and (2) the most impressive regeneration examples (especially spinal cord and brain).
Select the best match
Because few vertebrates can regenerate limbs, large sections of the spinal cord, and parts of the brain, the axolotl stands out among animals.
