Where and when will APAC 23 be held?

  1. A.Bharat Mandapam, New Delhi, 13-14 November 2026
  2. B.Yashobhoomi Convention Centre, New Delhi, 13-14 November 2026
  3. C.Pragati Maidan, New Delhi, 3-4 December 2026
  4. D.Chennai Trade Centre, 13-14 November 2026

Correct answer

B. Yashobhoomi Convention Centre, New Delhi, 13-14 November 2026

Explanation

The correct answer is the Yashobhoomi Convention Centre in New Delhi on 13 and 14 November 2026. The two-day conference will bring the Asia-Pacific mobility engineering community together at that venue. Option A keeps the right dates but shifts the venue to another Delhi convention centre, which is the commonest way such a question is set. Option C changes both the venue and the dates and is therefore wrong on two counts. Option D moves the conference to Chennai, which is plausible to a careless reader because the automotive industry has a large presence in Tamil Nadu, but the venue announced is in New Delhi. Along with the plenary and technical sessions, the venue will hold an Exposition, a Technology Theatre and the TechHive platform for mobility start-ups.

Q3.Science & TechnologyMedium

At APAC 23, which platform has been created specifically for mobility start-ups?

  1. A.Technology Theatre
  2. B.Exposition
  3. C.TechHive
  4. D.Digital Twin Pavilion
Show answer
Correct answer: C. TechHive

The correct answer is TechHive, described as a dedicated platform created to connect mobility start-ups with the wider automotive ecosystem, where emerging companies can show their innovations and meet industry leaders, technology experts, investors, possible customers and collaborators.

Q4.Science & TechnologyHard

Which structure was identified as the cause of the varying secondary emission lines in Centaurus X-3?

  1. A.The stellar wind of the companion star
  2. B.The surface of the neutron star
  3. C.The accretion stream
  4. D.A ring of dust around the binary
Show answer
Correct answer: C. The accretion stream

The team worked out that the structure responsible had to be rotating together with the pulsar, and the stream fits that description: as it swings between the pulsar and the observing satellite, the direct radiation from the pulsar weakens while the light re-emitted by the stream strengthens, producing the variation…

Q5.Science & TechnologyHard

Why is the finding about Centaurus X-3 considered unusual?

  1. A.A high-mass X-ray binary usually captures stellar wind directly instead of forming a disk
  2. B.The pulsar was found to have no magnetic field at all
  3. C.The companion star was found to be smaller than the Sun
  4. D.The system was found to lie outside our galaxy
Show answer
Correct answer: A. A high-mass X-ray binary usually captures stellar wind directly instead of forming a disk

In such pairs the companion is a massive star that sheds a strong wind, and the pulsar ordinarily feeds on that wind as it passes, so an orderly disk of matter is not expected.
