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.
