What are some ways in which people question and challenge long-
standing accepted beliefs today?

There are many examples in which people choose to ignore decades of discoveries, such as flat Earthers. This is caused by either two things. Number one is that these people are extremely uneducated and choose what to believe just because that is what they see, they don’t care what others see. In short, a narrowed perspective. Number two is that these people do know what they are talking about but decide to spread such false information just for attention, they don’t care what it does to their reputation, as long as they get more cash they call it winning.

Correct answer choice is:

C. A stopwatch

Explanation:

The best a decent eye will do is fix a reading to one tenth of a second, that is so the design of the stopwatch. The digital stopwatch has 2 digits on the far side the seconds, thus it further separates the time in hundredths of a second. Since it's simple to scan to hundredth of a second, that's its design.
