Show answer
Concept: Pick the idiom whose sense matches 'a breakthrough after stagnation'.
- The project is now doing very well, so we need an idiom of full efficiency.
- Firing on all cylinders = working at maximum power and effectiveness.
- 'Back to the drawing board' = starting again after failure; 'barking up the wrong tree' = wrong approach; 'skating on thin ice' = in a risky position.
Trick: Breakthrough = positive tone; three options are negative, only one is positive.
Answer: (B) firing on all cylinders
अवधारणा: खाली जगह में ऐसा idiom चाहिए जो 'breakthrough के बाद तेज़ प्रगति' दिखाए।
- प्रोजेक्ट अब पूरी ताकत से चल रहा है।
- Firing on all cylinders = पूरी क्षमता से काम करना।
- Back to the drawing board = फिर से शुरू करना; barking up the wrong tree = गलत दिशा में प्रयास; skating on thin ice = जोखिम में होना।
ट्रिक: वाक्य का भाव सकारात्मक है; बाकी तीनों idioms नकारात्मक हैं।
उत्तर: (B) firing on all cylinders
