passage IV

32. According to the fifth paragraph (lines 35–45), studies have shown that the insertion of acupuncture needles into acupoints causes nerve stimulation that results in:

  • F. signals being sent to the brain and pituitary gland, which leads to the release of chemicals.

  • G. signals being sent to the spinal cord, which imme- diately blocks the release of chemicals.

  • H. chemicals being released that amplify signals to the spinal cord.

  • J. chemicals being released that numb the spinal cord and prevent signals being sent to the brain and pituitary gland.
