Malaria has been rare during the past 60 years. Which option correctly reflects this statement?

• A. Malaria remains common today
• B. Malaria has been rare during the past 60 years
• C. Malaria is the most common mosquito-borne disease
• D. Malaria is transmitted by ticks

Answer: (B)

The main idea is reading a claim about how common malaria has been over time and picking the option that agrees with that claim. The best choice states that malaria has been rare during the past 60 years, which directly matches the given statement. Malaria is transmitted by Anopheles mosquitoes, not ticks, and while it has been greatly reduced in many regions due to control measures, it remains a problem in some tropical areas. The other options either contradict the rarity claim or misstate the transmission.
