Why the others are wrong
AThis choice describes the stone's physical characteristics and discovery but omits the critical information about how it enabled decipherment and its impact on the field of Egyptology.
BThis choice focuses on contemporary debates about repatriation rather than explaining the stone's historical significance for advancing the study of ancient Egypt.
DThis choice has a grammatical error with the non-parallel construction 'deciphered' and 'enabling' that fails to properly coordinate the sentence elements.
Question 24Hard
While researching a topic, a student has taken the following notes:
• The James Webb Space Telescope (JWST) launched in December 2021 to study the early universe.
• Its infrared instruments can detect light from galaxies formed within 200 million years after the Big Bang.
• Previous telescopes like Hubble could only observe galaxies formed 400 million years or more after the Big Bang.
• In 2022, JWST identified galaxy GLASS-z13, which formed approximately 300 million years after the Big Bang.
• This galaxy appears more massive than models predicted for that early period.
• The discovery challenges existing theories about the rate of early galaxy formation.
• Astrophysicist Emma Curtis-Lake notes that JWST observations may require revisions to cosmological models.
The student wants to explain the significance of the GLASS-z13 discovery. Which choice most effectively uses relevant information from the notes to accomplish this goal?
Show the answer and explanation
Why B is right
Choice B explains the significance by describing what GLASS-z13 is, when it formed, why it is surprising (more massive than predicted), and what implications this has for existing theories about early galaxy formation.
Why the others are wrong
AThis choice describes JWST's capabilities but does not address the GLASS-z13 discovery or its significance, focusing on the wrong part of the notes.
CThis choice mentions the discovery and Curtis-Lake's comment but omits the critical evidence of why the discovery is significant—that the galaxy is more massive than predicted and challenges formation theories.
DThis choice contains a subject-verb agreement error with 'observations...challenges' rather than 'observations...challenge,' making the sentence grammatically incorrect.
Question 25Hard
While researching a topic, a student has taken the following notes:
• Marine biologist Ayana Elizabeth Johnson studies coral reef conservation strategies.
• Traditional reef restoration involves transplanting coral fragments onto damaged reefs.
• This method can restore small areas but is labor-intensive and expensive at scale.
• Johnson advocates for a complementary approach: protecting existing healthy reefs from human stressors.
• Her 2019 research in the Caribbean found that reducing coastal pollution and overfishing allowed reefs to recover naturally.
• Natural recovery costs significantly less per hectare than active transplantation.
• Johnson argues that prevention should be prioritized alongside restoration efforts.
The student wants to present Johnson's argument for emphasizing reef protection. Which choice most effectively uses relevant information from the notes to accomplish this goal?
Show the answer and explanation
Why B is right
Choice B presents Johnson's complete argument for reef protection by combining her advocacy for protecting healthy reefs, the cost-effectiveness rationale, and her position that prevention should be prioritized, directly accomplishing the goal.
Why the others are wrong
AThis choice discusses traditional restoration methods but does not present Johnson's argument for emphasizing protection, using information from the wrong part of the notes.
CThis choice is grammatically incomplete, lacking a main verb to complete the sentence structure about the Caribbean research findings.
DThis choice introduces Johnson and her general research area but omits the specific argument for why protection should be emphasized, providing no supporting rationale.
