Practice one SAT question at a time

Questions come from the Bluebook question bank. Made by Iskaa303 (Iskander Madikhan).

While researching a topic, a student has taken the following notes:

  • Albert Einstein’s theory of general relativity allows for potential shortcuts through spacetime.
  • These hypothetical spacetime tunnels are known as wormholes.
  • For matter to travel through a wormhole, it would need to have negative energy density.
  • Negative energy density means that the matter would have less energy than empty space.
  • Such matter has not been shown to exist.

The student wants to acknowledge a complication affecting travel through wormholes. Which choice most effectively uses relevant information from the notes to accomplish this goal?
