Identify and describe three tests used to assess the health of an unborn baby
What will be an ideal response?
A good answer would include the following key points:
• Amniocentesis: done between the 15th and 20th week of pregnancy. This procedure examines a sample of amniotic fluid, which contains fetal cells. This test can identify a variety of genetic defects and can determine the sex of the child.
• Chorionic villus sampling (CVS): done at 8-11 weeks. This procedure involves inserting a thin needle into the fetus and extracting small samples of hairlike material that surrounds the embryo.
• Ultrasound sonography: Uses very high- frequency sound waves to detect structural abnormalities or multiple pregnancies, measure fetal growth, judge gestational age, and evaluate uterine abnormalities. Also used as an adjunct to other procedures such as amniocentesis.

A bomb exploded at the 1996 Olympic Games in Atlanta, Georgia, killing one and wounding more than 100. The FBI conducted an investigation and within days, Richard Jewell was identified as a suspect. After several months, the Justice Department announced that Jewell was no longer a suspect. Jewell was publicly scorned, and followed incessantly by the media and law enforcement for the three months that he was believed to be the bomber. Evidence in the case was interpreted in such a way as to support the idea that Jewell was guilty. For example, Jewell was known to have seen the bag containing the bomb before it detonated, and moved people from the area. This life- saving act was seen as evidence that he was the bomber, because the investigators believed that he had planted the bomb in order
to be able to be seen as a hero for saving people. The operation described in this case can be described as a(n)_____________. A. informal inquiry B. proactive investigation C. reactive investigation D. pretext investigation
