Analyze the question: You are asked for the word opposite in meaning to "antidote" in the sentence: "The presidential system is an antidote to some political ailments."

Explain the concept: An antidote is something that counteracts or cures a harmful thing, such as a poison or a problem. It is a remedy or a solution. Its opposite would therefore be something that worsens a problem or stands in the way of a cure, such as a hindrance or an obstacle.

Solution:

• A. an answer: This is close to "solution", so it is a synonym, not an opposite.
• B. an inquiry: This means a question or investigation. It is unrelated to "antidote" and is not its opposite.
• C. a reply: This is similar to an answer, so it is not opposite either.
• D. an obstacle: An obstacle blocks progress or solutions. An antidote helps solve the problem, while an obstacle hinders. This is the best opposite.

Answer: D. an obstacle

Tip: In "opposite meaning" questions, first work out the meaning of the word, then eliminate its synonyms. Often one or two options are synonyms placed there as traps, as A and C are here. Also, the tone of the word matters: antidote is positive (it cures), so look for a negative counterpart (a hindrance or something harmful).
