Answers With Explanation:

BCS Answers

01. Ans: B Explanation: Here 'perfect' modifies the verb 'diagnose', so it should be an adverb 'perfectly'. The correct phrase is "diagnose a problem perfectly".

02. Ans: D Explanation: The preposition 'by' should be followed by a gerund (verb+ing). It should be "by watching television" instead of "by watch".

03. Ans: D Explanation: 'Every man and woman' is a singular subject structure, so the possessive pronoun should be singular ('his or her'), not plural 'their'. However, in modern usage 'their' is often accepted as singular neutral, but strictly in exams, it acts as an error here for singular agreement.

04. Ans: A Explanation: The structure 'One of the' is followed by a plural noun. So it should be "One of the recommendations" instead of "recommendation".

PSC & Other Exam Answers

01. Ans: D

Explanation: There is no error in the sentence "Females are viewed as inferior to males in nations ruled by patriarchy.".

02. Ans: A Explanation: In an embedded question (a question inside a statement), the word order should be subject + verb, not verb + subject. It should be "where he could have gone", not "where could he have gone".

03. Ans: B Explanation: 'To be' should be followed by an adjective or noun. Here 'disrespect' is a noun but 'disrespectful' (adjective) fits better as a complement to 'be'. Or 'show disrespect'. The error lies in using "disrespect" where an adjective like disrespectful is expected.

04. Ans: A Explanation: The error is in A. "Agrarian industry" refers to agriculture. While "In the" is grammatically possible, "In the agrarian industry" might be considered awkward compared to "In agriculture". However, the provided answer key points to A. Note: The phrase "source of their incomes" (plural) might also be suspect, but A is marked.

05. Ans: C Explanation: When subjects are joined by 'together with', the verb agrees with the first subject. 'Karim' is singular, so the verb should be was, not 'were'.

06. Ans: A Explanation: 'Neither of the' is followed by a plural noun. It should be "Neither of the workers" instead of "worker".

07. Ans: D Explanation: In a "No sooner... than" structure, the second clause (after than) uses Past Indefinite. It should be "than the train left", not "had left".

08. Ans: D

Explanation: There is no error in the sentence.

09. Ans: C

Explanation: The idiom is "keep their eye on the ball", not "at the ball".

10. Ans: C Explanation: The phrase 'looking forward to' is followed by a gerund (verb+ing). It should be "looking forward to going".

11. Ans: B

Explanation: The subject "movements" is plural, so the verb should be were, not 'was' restrained.

12. Ans: B Explanation: The word 'particular' is an adjective, but an adverb is needed here to modify the phrase. It should be particularly.

TOPIC: PIN POINT ERROR

Pinpoint the Error

To pinpoint the error means to find out, identify, or indicate the incorrect part in a given sentence. The following questions ask you to identify which underlined part of the sentence is grammatically incorrect.

1. The only error in the sentence "One Of the recommendation made by the committee was accepted by the authorities" is- [33rd BCS] A. recommendation B. was C. accepted by D. committee Answer: A. recommendation Explanation: The phrase "One of the" must be followed by a plural noun.

According to experts B. to improve listening skills is to watch C. specially news D. documentaries Answer: C. specially news Explanation: The error is in the word 'specially'.

3. A doctor may be able to diagnose a problem perfect, but he may not be able to find a drug to which the patient will respond. [32nd BCS, RU (E, even) 14-15] A. A doctor may be able to B. diagnose a problem perfect C. find a drug D. will respond Answer: B. diagnose a problem perfect Explanation: The verb 'diagnose' should be modified by an adverb, not an adjective. Therefore, 'perfect' should be perfectly.

4. Every man and woman should vote for the candidate of their choice. [32nd BCS, CU (E) 11-12, RU (E, even) 13-14] A. Every man and woman B. should vote for C. the candidate D. their choice Answer: D. their choice Explanation: When "Every" is used with singular nouns joined by "and," the corresponding pronoun must also be singular. Therefore, 'their' should be his or her. In modern usage, 'their' is often accepted as a gender-neutral singular pronoun, but traditionally, 'his or her' is considered correct.

5. I don't know where could he have gone so early in the morning. [Pubali Bank Ltd. (JO)-13] A. where could he have gone B. so early C. in the morning D. No error Answer: A. where could he have gone Explanation: This is an embedded question, which should follow a statement word order (subject + verb), not an inverted question order. The correct phrasing is where he could have gone.

6. She is looking forward to go to Europe next month. [CU (D) 15-16] A. She is B. looking forward to C. go to D. next month Answer: C. go to Explanation: The phrasal verb "look forward to" must be followed by a gerund (verb + -ing). Therefore, 'go' should be going.

No error Answer: B. to be disrespect Explanation: The verb "to be" should be followed by an adjective. The adjective form of 'disrespect' (a noun) is disrespectful.

8. Neither of the worker was ready to work overtime causing the deadline to be missed. A. Neither of the worker B. was ready to C. overtime causing D. to be missed E. No error Answer: A. Neither of the worker Explanation: The phrase "Neither of the" must be followed by a plural noun. Therefore, 'worker' should be workers. The singular verb 'was' is correct because it agrees with 'Neither'.

9. No sooner had he reached the station than the train had left. A. No sooner had he reached B. the station C. than D. the train had left E. No error Answer: D. the train had left Explanation: The structure is: No sooner had + subject + V3 ... than + subject + V2 (Past Indefinite). Therefore, 'had left' should be left.

10. Parking his car at the market, Ms Jones decided to take the bus to town. A. Parking his car B. at the market, Ms Jones C. decided D. to take the bus to town E. No error Answer: A. Parking his car Explanation: This is a dangling modifier error. The subject of the main clause is "Ms Jones" (female), but the participle phrase "Parking his car" implies a male subject. It should be Parking her car.

11. Kahn together with many of his friends and relatives were present in the meeting. A. Kahn together with B. many of his friends and relatives C. were present D. in the meeting Answer: C. were present Explanation: When subjects are joined by phrases like "together with," the verb agrees with the first subject.

No Error Answer: B. particular of Explanation: The adjective 'particular' should be the adverb particularly to modify the prepositional phrase "of the societies."

In the agrarian industry B. the farmers nurture C. this land because D. the source of their incomes E. No Error Answer: A. In the agrarian industry Explanation: "Agrarian" relates to cultivated land or the cultivation of land. "Industry" usually refers to manufacturing. The phrase is redundant and slightly illogical.

Canals are B. either to transport C. or to delivering D. water to cities and farms Answer: C. or to delivering Explanation: This sentence has a parallel structure error.

Although a Kangaroo B. normally uses C. for hopping, D. but Answer: D. but Explanation: When a sentence begins with a subordinating conjunction like "Although," a coordinating conjunction like "but" should not be used to introduce the main clause.
