28. Select the word or phrase that makes this sentence grammatically correct: 'The blue whale is the largest animal in the world.'
Answer: B
The blue whale is the largest animal in the world.
The phrase "in the world" is the correct choice to complete the sentence, as it is the conventional way to refer to something within the entirety of the world.
A) of
Using "of" in this context would be grammatically incorrect. The phrase "the largest animal of the world" does not convey the intended meaning and is not a standard expression in English.
B) in
This option is correct because "in the world" is the appropriate prepositional phrase that indicates the blue whale's status relative to all other animals globally. It effectively communicates that the blue whale is the largest when considering all animals that exist.
C) at
The use of "at" would also be incorrect in this context. "The largest animal at the world" is not a grammatically correct phrase and fails to express the relationship of the blue whale to all animals worldwide.
D) on
Choosing "on" would not fit either, as "the largest animal on the world" does not make sense in English. The phrase implies a physical presence on a surface rather than a comparative status among animals.
Conclusion
The phrase "in the world" is the only option that accurately completes the sentence, maintaining the intended meaning and grammatical structure. All other options fail to convey the correct relationship or are not standard expressions, making them unsuitable for this context.
