The erroneous part of the sentence is: Make all decisions.

The erroneous part of the sentence is: And are not scared from them.

Key Points

• Replace the preposition "from" with "of" to correct the sentence.
• From is used to refer to the place where someone or something starts or originates.
  • Example - He is suffering from a headache.
• Of is used when we want to show that people or things relate to other things or people.
  • Example - He was bullying her and she was scared of him.
• Remember that after "afraid" and "scared" or when talking about fear, we use the preposition “of”.
• So, "scared of" should be used in the given sentence.

Therefore, the correct answer is option 3, which contains an error.

Corrected sentence: In some tribal areas, people worship snakes and are not scared of them.

• वाक्य को सही करने के लिए Preposition "from को "of" से बदलें।
• 'from' का उपयोग उस स्थान को संदर्भित करने के लिए किया जाता है जहां कोई या कुछ शुरू या उत्पन्न होता है।
  • For e.g.-  He is suffering from a headache.
• 'of' का उपयोग तब किया जाता है जब हम यह दिखाना चाहते हैं कि लोग या चीजें अन्य चीजों या लोगों से संबंधित हैं
  • For e.g.- He was bullying her and she was scared of him.
• याद रखें कि "डर" और "डर" के बाद या डर के बारे में बात करते समय, हम "के" पूर्वसर्ग का उपयोग करते हैं।
• अतः दिए गए वाक्य में "डरना" का प्रयोग होना चाहिए।

The erroneous part of the sentence is: Naturally superior than others.

Key Points 

• Replace the preposition "than" with "to" to correct the sentence.
• Than is a conjunction or preposition and is always used to introduce a comparison, often with words like bigger, fewer, less, older and younger, etc.
  • Example - I like cake better than pie.
• To is used to indicate the person or thing that receives or experiences the object of the verb.
  • Example - We have a relationship infinitely superior to those of many of our friends.
• The word Superior should not be used with 'than', Superior is always followed by the preposition 'to'.
• So, the preposition "to" should be used in the given sentence.

Therefore, the correct answer is option 1, which contains an error.

Corrected sentence: The myth that some races are naturally superior to others has now been fully demolished.

The erroneous part of the sentence is: Please wait inside the white line.

Key Points 

• Replace the preposition "inside" with "behind" to correct the sentence.
• Inside means in, on, or to the inner part or surface of something.
  • Example - Is there anything inside the box?
• Behind means in, at, or to the back of somebody/something.
  • Example - The sun went behind a cloud.
• The implied meaning of the sentence is: "To minimize excessive congestion, kindly wait behind the white line."
• So, the preposition "behind" should be used in the given sentence.

Therefore, the correct answer is option 1, which contains an error.

Corrected sentence: Please wait behind the white line to avoid unnecessary congestion.

The erroneous part of the sentence is: A noblest quality

Key Points

• Replace the article "a noblest" with "the noblest" to correct the sentence.
• The indefinite article (a) is used before a noun that is general or when its identity is not known.
• The definite article (the) is used before a noun to indicate that the identity of the noun is known to the reader.
• "Noblest" is the superlative adjective of "Noble" which means belonging to the highest social class.
• The superlative degree of an adjective always takes the definite article ‘the’ before it.
• So, we must use "the" before "noblest" in the given sentence.

Therefore, the correct answer is option 3, which contains an error.

Corrected sentence: The fight for liberation brings out the best and the noblest quality in mankind.

The erroneous part of the sentence is: When business are slow

Key Points

• Replace the verb  "are" with "is" to correct the sentence.
• A singular subject of a sentence or clause requires a singular verb.
• For example:
  • James are coming to the picnic. (Incorrect)
  • James is coming to the picnic. (Correct)
• In this question, the subject is 'business' (singular noun). Hence, the verb that must agree with it must also be singular (is).
• Hence, 'are' after 'business' must be replaced by 'is'.

Corrected sentence: He works in the Continental Shoemakers' factory and sneaks away to write poetry when business is slow.

The erroneous part of the sentence is: His obviously reluctance

Key Points

• Replace the adverb ‘obviously’ with the adjective ‘obvious’ to correct the sentence.
• An adverb is a part of speech that modifies another adverb, a verb, or an adjective. It is often recognized by the suffix -ly at the end of it.
• An adjective is a part of speech that modifies a noun or pronoun. Adjectives usually tell what kind, how many, or which about nouns or pronouns.
• In this given sentence, the adjective "obvious" should be used because it is describing the noun "reluctance".
• Reluctance means an unwillingness to do something.
  • Example - Tony left with obvious reluctance.

​Therefore, the correct answer is option 1, which contains an error.

Corrected sentence: His obvious reluctance was viewed seriously by his superiors and he was suspended. 

The erroneous part of the sentence is: finish your report

Key Points

• Replace "finish" with "finished" to correct the sentence.
• We use "will have" when we are looking back from a point in time in the future. So, the given sentence should be written in the future perfect tense.
• We use the future perfect tense to talk about something that will be completed before a specific time in the future.
• "By this time" is an expression can be used for a past, present or a future action and it means, "at some point before"
• The structure of the future perfect tense is: "Subject + will + have + past participle + the rest of the sentence"
  • Example - By the end of the decade, scientists will have discovered a cure for influenza.
• Therefore, "finished" should be used in the given sentence.

So, the correct answer is option 3, which contains an error.

Corrected sentence: You will have finished your report by this time next week.

The erroneous part is option 1) i.e. 'that he rarely eats.'

Key Points  

• The error lies in part 'that he rarely eats.'
• According to the rules of tense, the verb 'said' used at the beginning of the sentence shows that the speaker is mentioning an event from the past. Therefore in the later part, we have to also use the verb in the past form.
• Here the verb 'eats' is in its base form and it should be replaced with its past form 'ate.'
• Therefore in the given sentence, we need to use 'ate' in place of 'eats' to make the sentence grammatically correct.
• Hence, the correct answer is option 1.

Correct sentence: It is said of Mahatma Gandhi that he rarely ate non-vegetarian meals in his life.

The erroneous part is option 3) i.e. 'In India, the bravery of Rajputs (A).'

Key Points  

• The error lies in the first part 'In India, the bravery of Rajputs.'
• According to the rules of the articles, 'the' is used before caste and communities.
• Here 'Rajputs' is a community therefore use 'the' before it.
• In the given sentence, we need to use 'In India, the bravery of the Rajputs' in place of 'In India, the bravery of Rajputs' to make the sentence grammatically correct.
• Hence, the correct answer is option 3.

Correct sentence: In India, the bravery of the Rajputs and the devotion of the Brahmans seem to have afforded a stronger national bulwark than existed in western Europe.
