In which year did the APAC conference series begin, under the name International Pacific Conference?

  1. A.1971
  2. B.1981
  3. C.1991
  4. D.2001

Correct answer

B. 1981

Explanation

The correct answer is 1981. The series started in that year as the International Pacific Conference and has since grown into a collaborative automotive engineering forum representing 11 countries across the Asia-Pacific region. Options A, C and D are near decades offered to test whether the year has been memorised rather than guessed; none of them is given as the year of origin. Two other numbers from the same announcement are worth keeping separate from this one: the conference is the 23rd edition in the series, and India is hosting it for the second time after a gap of 15 years. Candidates should also remember the expected scale, which is more than a thousand delegates, over five hundred mobility experts, more than a hundred and fifty technical presentations and over eighty exhibitors.

  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.
