I believe it would be the shared experiences dilute traditional cultures. It can’t be the 2nd or 3rd answer because those are positives and it is asking for a negative effect, but I don’t think it is the 4th answer either because I don’t believe that being able to experience the same things would eliminate a culture entirely. Yes it could dilute it because we’d be almost overcoming cultural barriers by connecting through shared experiences throughout the world, but the effects of shared experiences don’t translate to things like genocides or systemic discrimination in an attempt to eliminate a culture.
