1./3./6. (I recommend you read my explanation)

Explanation:

1. Why a product could lose value over time could lose demand over time relates to supply, demand, and scarcity. Either the supply increases and can fit the demand or there is no demand for it.

3. Why consumers are willing to pay high prices for an item. Someone is only willing to pay a high price for an item if there is little supply and high demand. So for example, is like in a desert with a group of people and bidding over who gets the bottle full of water.

6. Why a single resource has more value than another. Being back to the previous example, in a sandy environment people wouldn't be bidding on who gets the most amount of sand because it's not a scarce resource.
