A lab has a new material they must test in order to determine its nature. Which test will determine whether the substance is a conductor, insulator, or semiconductor?
  1.A potential difference is applied; if the material conducts, it is a conductor.
  2.A potential difference equivalent to 1 eV is applied; if the material conducts, it is a semiconductor.
  3.An infinitesimal potential difference is applied to the material; if it doesn't conduct, it is an insulator.
  4.A potential difference is applied to the material, beginning with a very small one and increasing to values equivalent to 5 eV. It can be identified based on when it begins to conduct.

Question 2

An atom containing three outer-shell electrons is added to a Group IV semiconductor such as silicon. The result is
  1.a p-type semiconductor.
  2.an insulator.
  3.an n-type semiconductor.
  4.a conductor.

Though methadone is often used to treat dependency on other opioids, the drug itself can be abused. Crushing or snorting methadone can achieve the opiate "rush" desired by addicts. Improper use such as these can lead to a dangerous dependency on methadone. This drug now accounts for nearly one-third of opioid-related deaths.

A serious new warning has been established for pregnant women against taking ACE inhibitors during pregnancy. In the study, the risk of major birth defects in children whose mothers took ACE inhibitors during the first trimester was nearly three times higher than in children whose mothers didn't take ACE inhibitors. Physicians can prescribe alternative medications for pregnant women who have symptoms of high blood pressure.
