अशुद्धि पहचान और वाक्य-सुधार MCQ - उत्तर सहित अभ्यास प्रश्न

The correct answer is 'had left'. When two actions happened in the past, the action that happened earlier is normally expressed in the past perfect tense. Here, first the train left; later, we reached the station. Therefore the sentence should read: 'By the time we reached the station, the train had left.' The simple past 'left' does not clearly mark the earlier action, 'has left' wrongly connects the action to the present, and 'was leaving' changes the meaning.

The error is in option B. The subject of the sentence is 'quality', not 'apples'. The phrase 'of these apples' only tells us which quality is being discussed; it does not decide the verb. Since 'quality' is singular, the verb must also be singular: 'The quality of these apples is poor.' The other sentences follow standard concord rules: 'each' takes a singular verb, a committee acting as one unit takes 'has', and the verb after 'neither...nor' agrees with the nearer subject.

'Furniture' is an uncountable noun in standard English and is treated as singular. Therefore it takes the singular verb 'is', not the plural verb 'are'. The sentence also needs passive voice because the furniture is made of teak wood; it does not make anything itself. The correct form is 'The furniture in the room is made of teak wood.' Option D fixes both agreement and voice without changing the meaning.

Option B gives both corrections. Certain adjectives from Latin origin, such as 'senior', 'junior', 'superior' and 'inferior', are commonly followed by 'to', not 'than', in exam grammar. So the first sentence becomes 'He is senior to me.' In the second sentence, 'news' looks plural because it ends in -s, but it is treated as a singular uncountable noun. Therefore the verb must be singular: 'The news is true.'

The correct preposition is 'in'. In standard English, the adjective 'interested' is followed by 'in' when we name the subject or activity that attracts someone: 'interested in music', 'interested in science', 'interested in learning'. Here, 'learning computer programming' is a gerund phrase, so the sentence becomes: 'She is very interested in learning computer programming.' The other prepositions do not fit this fixed adjective-preposition pattern.
