The correct answer is option (A):
learnt...... wrong
The question presents a fill-in-the-blank sentence that describes a common learning experience: realizing that previous understanding or knowledge was incorrect. Let's analyze why "learnt...... wrong" is the most fitting completion.
The sentence states, "People learn something everyday, and a lot of times it's that what they ______ the day before was ______."
The first blank needs a verb that describes an action of acquiring knowledge or information. The second blank needs an adjective that describes the state of that previously acquired knowledge.
Let's consider the options:
1. "learnt...... wrong": "Learnt" is a past tense form of "learn." This fits the context of reflecting on what was acquired previously. "Wrong" is an adjective that directly indicates that the previous understanding was incorrect. This aligns perfectly with the idea of learning that something previously believed was mistaken.
2. "knew.........inappropriate": "Knew" is the past tense of "know." While people often learn things they previously knew were incorrect, the primary action described in the sentence is learning something *new* that invalidates previous knowledge. "Inappropriate" means unsuitable or not proper, which doesn't directly address the factual correctness of the prior information.
3. "sai......nonsense": "Sai" is not a standard English word in this context; it's likely a misspelling. Even if we assume it means "said," the second blank, "nonsense," implies the previous statement was foolish or absurd, which is a stronger and more specific criticism than simply being incorrect. The sentence focuses on the *learning* that a previous understanding was flawed.
4. " d discuss....inaccurate": "d discuss" is grammatically incomplete and nonsensical. Even if we interpret it as "discussed," the word "inaccurate" means not precise or correct. While "inaccurate" is a possibility for the second blank, the first blank still presents a grammatical issue. Furthermore, the act of discussing something doesn't directly imply the acquisition of knowledge in the same way "learn" does.
Comparing the options, "learnt...... wrong" most accurately and grammatically completes the sentence, conveying the common experience of discovering that prior knowledge or understanding was mistaken. The process of learning often involves correcting errors in our existing knowledge base.
