Q5951.Select the most appropriate option to substitute the underlined segment in the given
sentence. If there is no need to substitute it, select ‘No substitution required’.
She is being waited for you for two hours.
- Ahad wait
- Bhas been waiting
- CNo substitution required
- Dhave been waited
Show answer
Concept: An action that started in the past and is still continuing, with a period of time (for two hours), takes the Present Perfect Continuous: has/have + been + V-ing.
- Subject She is singular → has been.
- She is the one who is waiting (active), so the verb must be waiting, not passive being waited.
- Correct: She has been waiting for you for two hours.
- had wait is a wrong form; have been waited is passive and plural.
Trick: for + period / since + point of time with an ongoing action → has/have been + V-ing.
Answer: (B) has been waiting
अवधारणा: जो काम past में शुरू होकर अभी भी चल रहा है और साथ में समय-अवधि (for two hours) दी हो, वहाँ Present Perfect Continuous लगता है: has/have + been + V-ing.
- Subject She singular है → has been.
- इंतज़ार She स्वयं कर रही है (active), इसलिए waiting चाहिए, passive being waited नहीं।
- सही वाक्य: She has been waiting for you for two hours.
- had wait गलत रूप है; have been waited passive और plural है।
ट्रिक: for + अवधि / since + समय-बिंदु और काम जारी हो → has/have been + V-ing.

SUAVE

- despised (घृणित) और renounced (त्यागा हुआ) उल्टे अर्थ वाले हैं।

sentence. If there is no need to substitute it, select ‘No substitution required’.
The train was delayed in order to an accident.
- Asince
- Bowing to
- CNo substitution required
- Dbecause
Show answer
Concept: Before a noun (an accident) we need a prepositional phrase of cause such as owing to / due to / because of. In order to shows purpose and takes a verb.
- an accident is a noun phrase, not a clause.
- since and because are conjunctions – they need a full clause (subject + verb) after them.
- So only owing to fits: The train was delayed owing to an accident.
Trick: Cause + noun → owing to / because of; cause + clause → because / since; purpose + verb → in order to.
Answer: (B) owing to
अवधारणा: noun (an accident) से पहले कारण बताने के लिए owing to / due to / because of लगता है। In order to उद्देश्य बताता है और उसके बाद verb आती है।
- an accident noun phrase है, clause नहीं।
- since और because conjunctions हैं – इनके बाद पूरा clause (subject + verb) चाहिए।
- इसलिए केवल owing to सही: The train was delayed owing to an accident.
ट्रिक: कारण + noun → owing to / because of; कारण + clause → because / since; उद्देश्य + verb → in order to.

The two trains gave the illusion of been stationary.
- AThe two

The sword of Damocles
- Aa rare artifact
- Ban authentic sword
- Can impending threat
- Da poignant weapon

- From a Greek tale: Damocles sat on a throne with a sword hanging above him by a single hair.
- It shows that power and good fortune carry constant danger.
- So it means ‘an impending threat’, not a real or rare sword.
Yaad rakhein: Sword hanging by a hair over the head = ever-present danger.
Answer: (C) an impending threat

- यूनानी कथा: Damocles सिंहासन पर बैठा था और उसके ऊपर एक बाल से तलवार लटक रही थी।
- अर्थ – सत्ता और सौभाग्य के साथ हमेशा खतरा रहता है।
