Explanation:

Skill Practice 1

Step1: Count diseases per insect

• Mosquito: malaria, dengue fever, yellow fever → 3 diseases.
• Tick: Lyme disease → 1 disease.
• Kissing bug: Chagas disease → 1 disease.
• Tsetse fly: sleeping sickness → 1 disease.

Step2: Compare counts

Mosquito spreads 3 diseases, others spread 1. So mosquito spreads the most.

Check symptoms for each disease: malaria (body aches), Lyme disease (body aches), Chagas disease (body aches), dengue fever (body aches), yellow fever (body aches), sleeping sickness (body aches). Also, fever is present in malaria (fever, chills), Lyme disease (fever), Chagas disease (swelling fever), dengue fever (fever), yellow fever (fever, chills), sleeping sickness (fever).

The chart has a source note: "Source: Centers for Disease Control and Prevention". So readers can tell from this source citation.

Answer:

The mosquito is responsible for spreading the most diseases. We know this because it is associated with 3 diseases (malaria, dengue fever, yellow fever) in the chart, while the other insects (tick, kissing bug, tsetse fly) are each associated with only 1 disease.
