Select the most appropriate option that can substitute the underlined segment in the given sentence.
The young boy displayed an aptitude on scientific research.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. aptitude for.
The most appropriate option to substitute the underlined segment "aptitude on" in the sentence is "aptitude for".
"Aptitude for" this phrase is used to indicate a natural ability or talent in a particular area or field. It is the correct collocation when referring to a skill or talent in something specific.
The other options are incorrect because:
Aptitude at: Although it might seem plausible, it is less commonly used compared to "aptitude for" in this context.
Aptitude by: This is incorrect because "by" does not fit with "aptitude" in this context.
Aptitude in: While this can be used in some contexts, "aptitude for" is more appropriate when referring to a specific area or subject of skill.
Therefore, "aptitude for" is the most appropriate substitution.
