Q951.Identify the INCORRECTLY spelt word in the given sentence.
Generousity is a godly feature among many individuals on the earth.
- AGenerousity
- Bfeature
- Cgodly
- Dindividuals
Show answer
Concept: When an adjective ending in -ous becomes a noun, the 'u' is often dropped: generous → generosity.
- The correct spelling is Generosity (no 'u' after 'o').
- 'feature', 'godly' and 'individuals' are all spelt correctly.
- Correct sentence: Generosity is a godly feature among many individuals on the earth.
Trick: Similar pattern: curious → curiosity, generous → generosity, famous → fame. The '-ous' + '-ity' combination becomes '-osity'.
Answer: (A) Generousity
अवधारणा: जब -ous पर ख़त्म होने वाला adjective noun बनता है, तो अक्सर 'u' हट जाता है: generous → generosity.
- सही वर्तनी Generosity है ('o' के बाद 'u' नहीं)।
- 'feature', 'godly' और 'individuals' सही लिखे गए हैं।
- सही वाक्य: Generosity is a godly feature among many individuals on the earth.
ट्रिक: इसी तरह: curious → curiosity, generous → generosity; '-ous' + '-ity' = '-osity'।

A doubtful look or examination of one's motives.
- AIntrospect
- BSuspect
- CCircumspect
- DRetrospect
Show answer
Concept: Suspect (verb/noun) means to doubt someone's honesty or motives; as a noun it can mean a look or examination with doubt.
- The definition stresses doubt about motives → suspect.

- परिभाषा में मुख्य बात motives पर संदेह है → suspect।
- Introspect = अपने ही विचारों की जाँच (आत्मनिरीक्षण)।

Vivacious and enthusiastic
- AIntroverted
- BEffervescent
- CRowdy

- Vivacious + enthusiastic = lively and bubbly → effervescent.
- Introverted = shy, reserved (opposite idea).
- Rowdy = noisy and disorderly; Brazen = shameless, bold.
Trick: Think of a fizzing soft drink – full of bubbles and energy = effervescent person.

अवधारणा: Effervescent का शाब्दिक अर्थ है बुलबुलेदार (soda जैसा); व्यक्ति के लिए – जोशीला, उत्साह से भरा (vivacious and enthusiastic)।
- Vivacious + enthusiastic = जीवंत और उत्साही → effervescent।
- Introverted = अंतर्मुखी, शर्मीला (उल्टा अर्थ)।
- Rowdy = हुड़दंगी; Brazen = बेशर्म, ढीठ।

- Avarious government departments through all levels
- Bvarious government departments from all levels
- Cvarious government departments in all levels
- Dvarious government departments at all levels
Show answer
Concept: With the noun level (rank or tier in a hierarchy), the fixed preposition is at: at all levels, at the national level.
- Correct: …to various government departments at all levels…
- 'through', 'from' and 'in all levels' are not idiomatic for a position in a hierarchy.
- The sentence also uses 'at the Centre', parallel to 'at all levels'.
Trick: at + level/stage/point: at all levels, at this stage, at that point.
Answer: (D) various government departments at all levels
अवधारणा: Noun level (स्तर) के साथ सही preposition at है: at all levels, at the national level।
- सही: …to various government departments at all levels…
- 'through', 'from', 'in all levels' स्तर (hierarchy) के लिए सही प्रयोग नहीं हैं।
- वाक्य में 'at the Centre' भी इसी प्रकार है।

After his business failed, he had to reduce spending and adjust to a frugal lifestyle.
- Atighten his belt
- Bhit the nail on the head
- Clet the cat out of the bag
- Dkick the bucket
Show answer

- 'had to reduce spending' + 'frugal lifestyle' → tighten his belt.
- Hit the nail on the head = say exactly the right thing.
- Let the cat out of the bag = reveal a secret; kick the bucket = die.
Trick: Less food/money → tighter belt. Spending cut = belt tightened.
Answer: (A) tighten his belt
अवधारणा: Tighten one's belt = पैसों की कमी के कारण खर्च कम करना।
- 'had to reduce spending' + 'frugal lifestyle' → tighten his belt।
- Hit the nail on the head = बिल्कुल सही बात कहना।
- Let the cat out of the bag = राज़ खोलना; kick the bucket = मर जाना।

Black sheep
- ANaive

- CDisreputable

Show answer
Concept: Black sheep = a member of a family or group who is regarded as a disgrace; i.e. disreputable.
- The idiom describes someone with a bad reputation within a group → disreputable.
- Miscreant (wrongdoer) is close but too strong; the idiom is about bringing shame, not committing crime.
- Naive and Intelligent are unrelated.
Trick: 'Black sheep of the family' = the one who brings disgrace (bad name) to the family.

अवधारणा: Black sheep = परिवार या समूह का वह सदस्य जो बदनामी का कारण हो, अर्थात् disreputable (बदनाम)।
- समूह में बुरी प्रतिष्ठा वाला व्यक्ति → disreputable।

don’t find any error, mark ‘No error’ as your answer.
When my father will come, I will make sure that I discuss the possibilities of a new
business venture with him.
- ANo error
- BI discuss the possibilities
- CWhen my father will come
- DI will make sure
Show answer
Concept: In a time clause (when, before, after, until, as soon as) referring to the future, we use the simple present, not 'will'.
- Main clause already has future: 'I will make sure'.
- So the time clause should be: When my father comes.
- The other parts are correct.
Trick: When/if/until clause → no 'will'. 'When he comes, I will…'
Answer: (C) When my father will come
अवधारणा: भविष्य को बताने वाले time clause (when, before, after, until) में simple present आता है, 'will' नहीं।
- Main clause में पहले से future है: 'I will make sure'।
- इसलिए time clause होगा: When my father comes।
- बाकी हिस्से सही हैं।
ट्रिक: When/if/until वाले clause में 'will' नहीं लगता।

This is the group of leaders in whom the ruling government has placed its trust.
- Ano substitution
- Bin who the ruling government
- Cwith who the ruling government
- Don who the ruling government
Show answer
Concept: The verb phrase is place trust in someone; after a preposition the object form of the relative pronoun, whom, is used.
- 'has placed its trust in whom' → 'in whom the ruling government has placed its trust' – correct.
- 'who' is a subject form, so 'in who', 'with who', 'on who' are wrong.
- Also 'trust in' (not 'with/on') is the correct collocation.
Trick: Preposition + whom (never preposition + who).
Answer: (A) No substitution
अवधारणा: Phrase है place trust in someone; preposition के बाद relative pronoun का object रूप whom आता है।
- 'in whom the ruling government has placed its trust' – सही है।
- 'who' subject रूप है, इसलिए 'in who', 'with who', 'on who' गलत हैं।
- सही collocation 'trust in' है, 'with/on' नहीं।
ट्रिक: Preposition + whom (कभी preposition + who नहीं)।
