Q1

According to the DevDay evidence, how many weekly users does ChatGPT now reach?

  • · More than 35 million weekly users
  • · Roughly 2.2 billion weekly users
  • · About 500 million weekly users
  • ✓ More than 1.2 billion weekly users

The evidence states that ChatGPT now reaches more than 1.2 billion weekly users. It separately says more than 35 million people use OpenAI’s developer and coding tools each week.

ChatGPT now reaches more than 1.2 billion weekly users, according to the DevDay evidence.

Q2

What milestone did SpaceX’s Starship achieve on Flight 14?

  • · It launched an operational satellite fleet.
  • · It completed its first Mars landing attempt.
  • · It carried astronauts to the Moon for the first time.
  • ✓ It reached Earth orbit for the first time.

The evidence states that Starship reached Earth orbit for the first time on Flight 14. It also says the vehicle later splashed down, moving beyond suborbital demonstrations.

On Flight 14, SpaceX’s Starship reached Earth orbit for the first time.

Q3

A headline says the 19-second result proves quantum computers are now generally superior to today’s supercomputers. Based on the evidence, how should that claim be treated?

  • · Unrelated: the evidence only reports hardware control, not any timed comparison.
  • · Accurate: it proves broad superiority over today’s machines in everyday computing.
  • ✓ Too broad: the result shows advantage on a specialized, carefully chosen task only.
  • · Too weak: it says the conventional supercomputer also finished in 19 seconds.

The evidence says the quantum computer completed a specialized task in 19 seconds, versus an estimated 110 years for a conventional supercomputer. But it also says such comparisons depend on workload design and baselines and “do not imply broad superiority over today’s machines.” So the broad claim should be limited to the chosen task.

The 19-second quantum result shows advantage on a specialized task, not general superiority.

Q4

In a scenario where Europe reaches the 1,000-qubit target but fidelity, connectivity and error correction do not improve with capacity, what does the evidence imply?

  • · The shared financing would no longer support commercialization goals.
  • ✓ The qubit count alone would not be enough to make the milestone matter.
  • · The initiative would return Europe to laboratory prototypes instead of infrastructure.
  • · The program would automatically beat American and Chinese quantum efforts.

The evidence says four-digit qubit counts matter only if fidelity, connectivity and error correction improve with capacity. So in the stated scenario, reaching 1,000 qubits by itself would not satisfy the condition that makes the milestone meaningful.

A 1,000-qubit goal matters only with better fidelity, connectivity and error correction.

Q5

Which conclusion is strictly supported by the evidence about SpaceX's Starship?

  • ✓ Starship reached orbit for the first time on September 29, 2026.
  • · Starship was declared ready for routine orbital missions after the flight.
  • · Starship had reached orbit before September 29, 2026.
  • · Starship completed its first crewed orbital mission on September 29, 2026.

The evidence says that on September 29, 2026, SpaceX's Starship spacecraft successfully reached orbit for the first time. It does not mention a crewed mission, any earlier orbital success, or readiness for routine missions.

On September 29, 2026, Starship reached orbit for the first time.
