Select the most appropriate adjective to fill in the blank.
The Nile is the _________ river in the world.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. longest.
Context: The sentence is: “The Nile is the _________ river in the world.”
Here, we are comparing the Nile to all other rivers in the world, so we need the superlative form of the adjective “long.”
Meaning of the words:
-
long – base form, does not indicate comparison.
-
most long – incorrect formation; the superlative of short adjectives like “long” is formed by adding -est, not “most.”
-
longer – comparative form, used for comparing two things, not all.
-
longest – superlative form, correctly indicates it is longer than all other rivers.
Correct word: longest
Final Sentence: The Nile is the longest river in the world.
Hence, the chosen option is correct.
