Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2. i.e.. infects.
Blank 1 Word Type: Verb (Present simple)
Explanation: The subject is "Yellow fever", which is a disease, so the correct verb should mean "to cause infection". Among the options:
Transmits means "to send or pass something on", but diseases infect, not transmit directly.
Infects is the correct verb used when a disease affects someone.
Passes is too vague.
Poisons mean causing harm through toxins, not suitable here.
Correct Sentence: Yellow fever, for example, infects humans, but can also infect monkeys.
Conclusion: The correct option is infects.
