Question 2

In the position-entanglement experiment, one of the two particles impacts at a particular point on one of the screens. Is the other particle affected by this observation, and if so, how?
 
  A) Yes, the other particle then ceases to feel the force exerted by the first particle.
  B) Yes, the other particle immediately makes a transition into a different quantum state, even though the two particles are some distance apart.
  C) Yes, the other particle transitions into a new quantum state a little later, after the force exerted by the first particle has had time to reach the second particle.
  D) No, the other particle is not affected because they are separate particles.
  E) No, the other particle is not affected because observations such as the impact of a particle cannot in themselves alter other objects in the real physical world.

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.
