Question 40

The main topic of the passage is foodborne illnesses.

The passage primarily discusses foodborne illnesses, detailing how they are contracted, their symptoms, and common sources of contamination, thereby establishing this as the central focus of the text.

A) foodborne illnesses

This option accurately reflects the main topic of the passage, which is dedicated to explaining foodborne illnesses, their causes, and effects. The extract provides extensive information on how these illnesses are contracted and the role of various food items in their occurrence.

B) the dangers of uncooked food

While the passage does mention that raw foods are a common source of foodborne illnesses, it does not exclusively focus on the dangers of uncooked food. Instead, it encompasses a broader discussion about various sources and types of foodborne illnesses, making this option too narrow to be correct.

C) bacteria

Although bacteria are highlighted as a significant cause of foodborne illnesses, the passage does not solely concentrate on bacteria. It addresses viruses, parasites, and harmful chemicals as well, which makes this option incomplete in capturing the main topic.

D) proper food preparation

Proper food preparation is briefly mentioned in the context of preventing foodborne illnesses, but it is not the main focus of the passage. The primary emphasis is on the illnesses themselves rather than the methods of preparation, rendering this option inaccurate.

Conclusion

In conclusion, option A is definitively correct as the passage centers on foodborne illnesses, discussing their causes, symptoms, and sources. The other options fail to encapsulate the broader context of the topic, focusing instead on more specific aspects that do not represent the overall message of the text.
