Practice one SAT question at a time

Questions come from the Bluebook question bank.

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

  • Some atoms contain an excess of neutrons.
  • Often, these neutrons form a “skin” on the atom’s surface.
  • An atom of lead-208 has a neutron skin.
  • The thickness of its neutron skin is approximately 0.28 trillionths of a millimeter.

The student wants to emphasize the thickness of lead-208’s neutron skin. Which choice most effectively uses relevant information from the notes to accomplish this goal?
