Official Solution:

• Offline access was enabled only on prototypes that also had biometric login.

Sort by the  Offline access  column and look at the prototypes with “Yes.” These are Aurora, Drift, and Flux.

Now check the  Biometric login  column for these three prototypes. All three also have “Yes.”

Therefore, the statement is true.

Answer:  Yes .

• Any prototype with voice control but without offline access also had biometric login.

Sort by the  Voice control  column and look at the prototypes with “Yes.” From these, keep only the prototypes with “No” under  Offline access . These are Beacon, Cobalt, and Echo.

Now check the  Biometric login  column for these three prototypes. Cobalt has “Yes,” but Beacon and Echo have “No.”

Therefore, the statement is not true.

Answer:  No .

• Every prototype with exactly two of the three features included biometric login.

Sort by the  Biometric login  column and look at the prototypes with “No.” These are Beacon, Echo, and Ion.

For any of these prototypes to have exactly two of the three features, it would need to have “Yes” for both  Offline access  and  Voice control . None of them does.

Therefore, no prototype with exactly two features lacks biometric login. Thus, every prototype with exactly two of the three features includes biometric login.

Answer:  Yes .
