In each of this question choose the option opposite in meaning to the word or phrase underlined The Novel laureate's activity in the field of science is heinous

Analyze the question: The question asks for the word opposite in meaning to "heinous" (an antonym). The sentence is: "The Nobel laureate's activity in the field of science is heinous."

Explain the concept: "Heinous" means extremely wicked, shocking, or hateful, as in a heinous crime. Its opposite is something praiseworthy, admirable, or good.

Solve step by step:

• A. Laudable means deserving praise or admiration. This is the opposite of heinous.
• B. Deplorable means shockingly bad or regrettable. This is similar to heinous, so it is a synonym.
• C. Forgettable means easily forgotten. It has no connection to moral judgment.
• D. Indelible means unable to be erased or removed, as in an indelible mark. It is unrelated.

Only laudable carries the opposite idea: heinous is condemned, while laudable is praised.

Answer: The correct option is A. Laudable.

Tip: In antonym questions, first decide whether a word is positive or negative. "Heinous" is strongly negative, so look for a positive option. Be careful about the option that is also negative (here, "deplorable"), because it is a synonym and a common trap. Remember that "laud" means "praise", as in "applaud".
