Which statement about prenatal rubella is true?
- A. The greatest damage occurs when rubella strikes during the fetal period.
- B. The organ damage inflicted by prenatal rubella can lead to lifelong health problems.
- C. Routine vaccination has made new rubella outbreaks extremely rare worldwide.
- D. Infection during the embryonic period is less harmful than during other prenatal periods.
Correct Answer: B
Rationale: The statement that the organ damage inflicted by prenatal rubella can lead to lifelong health problems is true. Rubella infection during pregnancy can cause serious harm to the developing fetus, including organ damage, deafness, heart defects, and intellectual disabilities. This highlights the importance of prevention and vaccination to protect both pregnant women and their unborn babies from the harmful effects of rubella.

The two main types of designs used in all research on human behavior are __________ and __________.
- A. observational; experimental
- B. correlational; experimental
- C. observational; correlational
- D. variable; observational
Correct Answer: B
Rationale: The two main types of designs used in all research on human behavior are correlational and experimental.

These two types of designs are fundamental in understanding and studying human behavior.
