Understanding Sentence Correction and Grammar Substitution The question asks us to select the most appropriate option to substitute the underlined segment "is learnt to play" in the sentence: "Sonia is learnt to play the guitar these days." If no substitution is needed, we should select "No improvement". Analyzing the Original Sentence The original sentence is "Sonia is learnt to play the guitar these days." Let's break down the underlined part "is learnt to play" and the context "these days". "is learnt": "learnt" is the past participle of "learn". The structure "is + past participle" typically forms the passive voice (e.g., "The lesson is learnt"). However, the sentence structure and the subject "Sonia" indicate an action that Sonia herself is doing (learning the guitar), not something being done to her. Therefore, the passive voice is not appropriate here. "to play": This is an infinitive phrase, correctly used after verbs related to learning skills (e.g., learn to swim, learn to drive, learn to play). "these days": This time phrase indicates an action that is happening currently or is ongoing over a period that includes the present. This typically calls for a continuous tense, often the present continuous tense. Combining these points, the structure "is learnt" is grammatically incorrect for expressing an ongoing active action in the present. The sentence requires an active verb form that fits the time frame "these days". Evaluating the Options for Substitution Let's look at the given options: 1. was learning to play This option uses the past continuous tense ("was learning"). While "learning to play" is the correct structure for the action, the past continuous tense refers to an action that was ongoing in the past. The time phrase "these days" refers to the present or a period including the present, not the past. Therefore, this option is not appropriate. 2. No improvement As we analyzed, the original sentence "Sonia is learnt to play..." is grammatically incorrect. The structure "is learnt" is wrong in this active context. Therefore, improvement is needed, and this option is incorrect. 3. is learning to play This option uses the present continuous tense ("is learning"). The present continuous tense is used for actions happening at the moment of speaking or for actions that are ongoing around the present time, often indicated by phrases like "these days," "now," "currently," etc. The structure "learning to play" correctly expresses the action of acquiring the skill. This option fits the context and time phrase perfectly. 4. was learning playing This option uses the past continuous tense ("was learning"), which is incorrect for "these days". Furthermore, the structure "learning playing" is grammatically incorrect; the correct idiom is "learn to play". Therefore, this option is inappropriate. Determining the Correct Substitution Based on the analysis, the sentence describes an action that is currently ongoing ("these days"). The correct tense for an ongoing action around the present is the present continuous tense (is/am/are + verb-ing). The correct way to express acquiring the skill of playing an instrument is using the idiom "learn to play". Combining these, the appropriate substitution is "is learning to play". The corrected sentence would be: "Sonia is learning to play the guitar these days." Original Appropriate for Correct Idiom Tense/Structure Segment "these days"? Used?

It indicates that something is happening currently or is a current state of affairs or activity. When used to describe an ongoing action or a temporary situation, it often pairs with the present continuous tense. Examples: They are building a new park in the town square these days. (Ongoing action) Many people are working from home these days. (Temporary situation/Ongoing activity) He is reading a lot of history books these days. (Activity happening in the current period) While "these days" can sometimes be used with the simple present tense to describe habits or general truths that are current, the present continuous tense is more common for describing temporary, ongoing actions or situations. In the context of learning a skill like playing the guitar, it's an ongoing process happening over a period of time that includes the present, making the present continuous tense the most suitable choice.
