Select the statement that is not true about bartering. Bartering can be more time-consuming than trading with money. Bartering encourages specialization. It's difficult to determine fair values for goods and services.

The correct answer is Bartering encourages specialization

That's because it is true that bartering is more time consuming since it usually does not end at a simple paying, but rather it includes negotiations and price changes and it takes more time. It is difficult because items get compared to each other and to other items and their values changes based on the individual trade, so paying with money is more efficient. This leaves the second answer as the correct one.
