A.I. Explanation:

Option 1: "They offer a purely chance-based outcome."

Explanation: This option is incorrect because the text emphasizes that board games offer a unique combination of strategy, skill, and chance, rather than being purely chance-based. The mention of strategy and skill indicates that the outcome is not solely based on chance.

Option 2: "They require less time than digital games."

Explanation: This option is incorrect as the text does not mention the time required to play board games compared to digital games. Therefore, it cannot be concluded that board games require less time.

Option 3: "They are more affordable than digital entertainment."

Explanation: This option is incorrect because the text does not provide any information regarding the affordability of board games compared to digital entertainment. Thus, this statement lacks support from the text.

Option 4: "They provide tangible social interactions."

Explanation: This option is correct as the text explicitly states that the resurgence of board games is partly attributed to the desire for tangible social interactions, which digital platforms cannot fully replicate. This aligns with the primary reason for their increasing popularity.
