Answer to Question 1

B

Answer to Question 2

The following strengths of scientific observation are listed in the text: representative sampling of subjects, controlled conditions, objective and systematic procedures, publication of findings, and replication (measurement issues might also be stressed). The following limitations are also listed in the same section: the limited number of factors/variables studied, conditions so controlled that the situation is very unlike the classroom, complex interactions among several classes of variables that make predicting and controlling outcomes difficult, disagreement on the interpretation of data/results, and the need to revise knowledge and applications in light of new research findings.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
