Identify the errors in the given sentences.

Here are the errors in each part with reasons and solutions:

12. On receiving the mark-sheet from the university (a)/I realised (b)/that I had got only passing marks in English. (c)/No Error (d)

• Error: No error.
• Reason: The sentence is grammatically correct and well-structured.
• Solution: No error

13. All her family members (a)/are great admirers of (b)/Virat Kohli (c)/and M.S Dhoni (d)/No error (e)

• Error: No error.
• Reason: The sentence is grammatically correct. "Family members" is plural, so "are" is correct. "Admirers of" is the correct preposition.
• Solution: No error

14. People must know (a)/that the wages of sin (b)/are nothing but death (c)/or troublesome life. (d)/No error (e)

• Error: Part (c)
• Reason: The phrase "the wages of sin" is a fixed idiom, and "wages" in this context refers to a singular outcome or consequence. Therefore, the verb should be singular.
• Solution: Change "are nothing but death" to "is nothing but death". The correct sentence is: "People must know that the wages of sin is nothing but death or troublesome life."

15. When Mohit got back from Kashmir (a)/he said that he had never (b)/seen such a wonderful (c)/spectacies in his life before. (d)/No error (e)

• Error: Part (d)
• Reason: "Spectacies" is not a correct English word. The correct word for an impressive sight or display is "spectacle" (singular) or "sights" (plural). Given "a wonderful", the singular form is appropriate.
• Solution: Change "spectacies" to "spectacle". The correct sentence is: "When Mohit got back from Kashmir he said that he had never seen such a wonderful spectacle in his life before."

16. Ali his sister-in-laws (a)/have got ethereal beauty, (b)/so for me it is very (c)/difficult to choose one cf (d)/them to tie knot with (e)/No error (e)

• Error: Part (a)
• Reason: The plural form of a compound noun like "sister-in-law" is formed by pluralizing the main noun, not the suffix.
• Solution: Change "sister-in-laws" to "sisters-in-law". The correct sentence starts: "Ali his sisters-in-law have got ethereal beauty..." (Note: There are other errors in parts (d) and (e) as well, but the first error is in (a)).

17. She has to leave for Patna (a)/tomorrow for an urgent work, (b)/so get a ticket (c)/booked for her. (d)/No error (e)

• Error: Part (b)
• Reason: "Work" is generally an uncountable noun. We do not use an indefinite article ("an") before it in this context.
• Solution: Change "an urgent work" to "urgent work" or "an urgent piece of work". The correct sentence is: "She has to leave for Patna tomorrow for urgent work, so get a ticket booked for her."

18. Many passer-by (a)/stopped at (b)/the place of the accident. (c)/No error (d)

• Error: Part (a)
• Reason: The plural form of the compound noun "passer-by" is "passers-by".
• Solution: Change "passer-by" to "passers-by". The correct sentence is: "Many passers-by stopped at the place of the accident."

19. The name of (a)/Amitabh's (b)/and Ajitabh's (c)/father is Bachchanji (d)/No error (d)

• Error: Part (c)
• Reason: When two or more nouns share a common possession, the possessive form ('s) is applied only to the last noun in the series.
• Solution: Change "Ajitabh's" to "Ajitabh". The correct sentence is: "The name of Amitabh and Ajitabh's father is Bachchanji."

20. There is so many filths (a)/all around (b)/the place. (c)/No error (d)

• Error: Part (a)
• Reason: "Filth" is an uncountable noun, so "many" should be replaced with "much". Also, "filths" is not the correct plural form; "filth" is used for both singular and plural.
• Solution: Change "many filths" to "much filth". The correct sentence is: "There is so much filth all around the place."

21. According to state government's estimates (a)/at least eight millions tones of rice (b)/will have to be imported (c)/this year because of a poor monsoon. (d)/No error (e)

• Error: Part (b)
• Reason: When a specific number (like "eight") precedes a unit of quantity (like "million"), the unit itself should be in its singular form. Also, "tones" should be "tons".
• Solution: Change "millions tones" to "million tons". The correct sentence is: "According to state government's estimates at least eight million tons of rice will have to be imported this year because of a poor monsoon."

22. Children enjoy listening to (a)/ghosts stories (b)/especially on Halloween. (c)/No error (d)

• Error: Part (b)
• Reason: "Ghost stories" is a common compound noun referring to a type of story. The plural form "ghosts" is not typically used as an adjective in this context.
• Solution: Change "ghosts stories" to "ghost stories". The correct sentence is: "Children enjoy listening to ghost stories especially on Halloween."

23. Some of his (a)/luggages were lost (b)/in the train. (c)/No error (d)

• Error: Part (a)
• Reason: "Luggage" is an uncountable noun and does not have a plural form "luggages".
• Solution: Change "luggages" to "luggage". The correct sentence is: "Some of his luggage was lost in the train." (Note: The verb "were" would also need to change to "was" to agree with the uncountable noun "luggage").

24. Bengali people (a)/do eat fishes every day, (b)/but she does not (c)/like it at all. (d)/No error (e)

• Error: Part (b)
• Reason: When referring to fish as food, the word "fish" is typically used for both singular and plural. "Fishes" is generally used when referring to different species of fish.
• Solution: Change "fishes" to "fish". The correct sentence is: "Bengali people do eat fish every day, but she does not like it at all." (Note: There is also an issue with the pronoun "she" in part (c) not agreeing with "Bengali people", but the first error is in (b)).
