Answer: Option A. -> 1

 -  Climbing Mount Fuji. Articles are not used before the name of mountain.

The given sentence is grammatically incorrect because of the use of the definite article "the" before "Mount Fuji". Here are some key points to consider:

• Mount Fuji is a proper noun, which means it is the name of a specific mountain. When we use a proper noun, we do not use an article with it unless it is part of the name itself (e.g. "The United States").
• In this case, "Mount Fuji" is the name of the mountain, so we should not use the definite article "the" before it. We should simply say "Climbing Mount Fuji".
• Using "the" before "Mount Fuji" implies that there are multiple Mount Fujis and the speaker is referring to a specific one. However, this is not the case. There is only one Mount Fuji, so we should not use the definite article.

Formula:

Article usage with Proper Nouns:

• Use the definite article "the" with a singular or plural noun when it is specific or particular.
• Do not use any article before a proper noun, unless it is part of the name itself.

Example:

• The Statue of Liberty (specific)
• The Eiffel Tower (specific)
• Mount Everest (not specific)

In conclusion, the correct sentence is "Climbing Mount Fuji in winter can be very dangerous."

Answer: Option D. -> 4

 -  ‘the habit of smoking’ in place of ‘habit of smoking’ 

In this sentence, the subject is "every man, woman, and child" and it is singular, so the verb "is" is correct in Part 2. Part 3 is also correct because "consequences" is plural and matches the verb "is".

However, in Part 4, the article "the" is missing before "habit of smoking". "The habit" refers to a specific habit that is being discussed, which is smoking in this case. Without "the", the sentence is incomplete and sounds awkward.

Therefore, the correct sentence would be:

"Every man, woman, and child is now aware of the terrible consequences of the habit of smoking."

Here are some relevant definitions and formulas to keep in mind while analyzing sentences for errors:

Subject: The subject of a sentence is the noun or pronoun that the sentence is about. It usually comes before the verb. In this sentence, the subject is "every man, woman, and child."

Verb: The verb is the action word or state-of-being word in the sentence. In this sentence, the verb is "is."

Article: An article is a word that comes before a noun and indicates whether the noun is specific or general. "The" is a definite article, indicating that the noun it modifies is specific. "A" and "an" are indefinite articles, indicating that the noun is general.

Agreement: Subject-verb agreement is the grammatical rule that requires the verb to agree with the subject in number. If the subject is singular, the verb must also be singular. If the subject is plural, the verb must also be plural.

Answer: Option D. -> 4

 -  ‘in the eastern’ in place of ‘in eastern’

The error in the sentence is the use of the preposition "in" after the word "eastern part" in part (4) of the sentence. When we refer to a specific part of a country, we use the preposition "of" instead of "in". Hence, the correct sentence should be:

The new railway line will greatly improve transport and communication in the eastern part of the country.

Here, "the eastern part of the country" is a specific region, and the preposition "of" is used to show that it is a part of the country.

Let's understand the usage of prepositions "in" and "of" in detail:

• "In" is used to refer to a place that is enclosed or inside something. For example, "I am in the room."
• "Of" is used to indicate a relationship between two things, or to show possession or origin. For example, "The cover of the book" or "The people of the town".

In the given sentence, we are referring to a specific region, which is a part of the country. Hence, the correct preposition to use is "of".

Formula:

The correct preposition to use when referring to a specific part of a country is "of", not "in".

In conclusion, the correct answer is option (D), and the error in the sentence is in part (4), where the preposition "in" is used instead of "of".

Answer: Option D. -> 4

 -  ‘a long time’ in place of ‘the long tome’

The given sentence is in the past tense, and it talks about an action that was completed in the past. Hence, the present perfect tense "have been awaiting disposal" is not appropriate here. Instead, the past perfect tense "had been awaiting disposal" should be used to indicate an action that had been going on in the past and was completed before the past action "started working" began.

Therefore, the correct sentence would be "that had been awaiting disposal for a long time."

The correct sentence after correction:

Having finished his breakfast (1)/ he started working (2)/ on the problem (3)/ that had been awaiting disposal for a long time. (4)/ No error.

To summarize:

• The error in the given sentence is in Part 4: "that have been awaiting disposal for the long time."
• The present perfect tense "have been awaiting disposal" is not appropriate here as the sentence is in the past tense.
• The past perfect tense "had been awaiting disposal" should be used to indicate an action that had been going on in the past and was completed before the past action "started working" began.
• Therefore, the correct sentence is "that had been awaiting disposal for a long time."
• Hence, the answer is option D: 4.
