- DA good and useful invention
Show answer
Concept: The idiom fit as a fiddle describes a person who is in excellent physical health.

Answer: (B) To be in good health
अवधारणा: Idiom fit as a fiddle का अर्थ है – पूरी तरह स्वस्थ होना।
- अच्छी तरह tune किया हुआ fiddle (वायलिन) बिल्कुल ठीक काम करता है; वैसे ही 'fit as a fiddle' व्यक्ति पूरी तरह स्वस्थ होता है।
- उदाहरण: Even at eighty, my grandfather is fit as a fiddle.

sentence.
It is important to see school holistically, it is not a set of atomic items of rooms, library, assembly halls, canteen and playgrounds; it is all of these but in symbiotic
relationship with each other, the contors of which are often far too obvious and often simply mysterious.
- Amysterious
- Bsymbiotic
- Ccontors
- Dholistically
Show answer
Concept: Check each underlined word against its standard spelling.
- holistically, symbiotic and mysterious are correctly spelt.
- contors is wrong; the correct word is contours (outlines/shape of something).
- So the incorrectly spelt word is 'contors'.
Yaad rakhein: Contour = con + TOUR (the 'u' is needed).
Answer: (C) contors
अवधारणा: हर underlined शब्द की सही वर्तनी जाँचें।
- holistically, symbiotic और mysterious सही लिखे हैं।
- contors गलत है; सही शब्द है contours (रूपरेखा/आकृति)।
- अतः गलत वर्तनी वाला शब्द 'contors' है।
याद रखें: Contour में 'tour' छिपा है – u ज़रूरी है।

Q2356.The following sentence has been split into four segments. Identify the segment that contains an error.
Will Ramya / had completed / that work / by 2025?
- Aby 2025
- Bthat work
- Chad completed
- DWill Ramya
Show answer
Concept: An action that will be finished before a stated future time (by 2025) takes the future perfect: will + have + V3.

- The question begins with Will, so the verb must be have completed, not had completed.
- Had + V3 is past perfect and cannot follow will.
- Correct: Will Ramya have completed that work by 2025?
Yaad rakhein: By + future time → will have + V3.
Answer: (C) had completed
अवधारणा: भविष्य के किसी समय (by 2025) से पहले पूरा होने वाले कार्य के लिए future perfect: will + have + V3।

- वाक्य Will से शुरू है, इसलिए had completed नहीं, have completed आएगा।
- Had + V3 past perfect है, यह will के बाद नहीं आता।
- सही: Will Ramya have completed that work by 2025?
याद रखें: By + भविष्य का समय → will have + V3.

- It comes from the Greek myth of the golden apple that started a quarrel among goddesses (and led to the Trojan War).
- Bone of contention has the same meaning – a subject of dispute.
- (D) 'centre of attraction' is the trap; that is closer to apple of one's eye (a dearly loved person).

Answer: (C) Bone of contention
अवधारणा: Apple of discord का अर्थ है – झगड़े की जड़।
- यह यूनानी कथा के सोने के सेब से आया है जिसने देवियों में झगड़ा कराया।
- Bone of contention का भी यही अर्थ है – विवाद का विषय।
- (D) 'centre of attraction' भ्रम पैदा करता है; वह apple of one's eye (अत्यंत प्रिय) से मिलता है।
याद रखें: Discord = झगड़ा, इसलिए apple of discord = झगड़े की जड़।

They knew that the stock of the food was getting reduced and the fund________for that was not enough for the next week.
- Aasserted
- Ballotted
- Calerted
- Dabandoned
Show answer
Concept: Funds are allotted (assigned/set aside) for a purpose.
- The sentence says the money set aside for food was not enough – 'the fund allotted for that'.
- Asserted = stated firmly; alerted = warned; abandoned = left behind – none fits 'fund'.
- Spelling: allotted (double t).
Yaad rakhein: Fund/time/seats are 'allotted'.
Answer: (B) allotted
अवधारणा: किसी काम के लिए धन allotted (आवंटित) किया जाता है।
- वाक्य कहता है कि भोजन के लिए रखा गया fund अगले सप्ताह के लिए पर्याप्त नहीं था – 'the fund allotted for that'।
- Asserted = ज़ोर देकर कहा, alerted = सचेत किया, abandoned = छोड़ दिया – fund के साथ अर्थहीन।
- वर्तनी: allotted (दो t)।
याद रखें: Fund, समय, सीटें – सब 'allotted' होते हैं।
