Correct Answer:
B. Lessen
The synonym of 'Mitigate' is 'Lessen'. To 'mitigate' means to make something less severe, serious, or painful. It implies reducing the intensity, impact, or harshness of a negative situation or condition. The goal of mitigation is to alleviate or soften a problem, rather than to eliminate it entirely.
For instance, if a government implements policies to mitigate the effects of a recession, they are trying to lessen the negative economic impact on citizens. Similarly, pain medication is used to mitigate discomfort, making it less severe.
Let's consider the other options:
- A: 'Worsen' means to make something worse or more severe, which is the direct opposite, or an antonym, of 'mitigate'.
- B: 'Lessen' perfectly captures the meaning of making something smaller in amount, degree, or intensity, aligning directly with 'mitigate'.
- C: 'Increase' means to make something larger in amount or degree, which is also an antonym of 'mitigate'.
- D: 'Aggravate' means to make a problem, injury, or offense worse or more serious, making it another antonym.
Therefore, 'lessen' is the most accurate synonym for 'mitigate', as both words convey the idea of reducing severity.
