Answer:
The answer is true.
Explanation:
It is true that the investment worth is $1000 because it is given that there is a negative 50 percent yield in the first year and in the second year there is a positive 50 percent yield. Here, negative yield shows some kind of loss and positive yield shows gains. So the loss of first-year is compensated by the gain of the second year. Therefore, the investment worth remains the same at $1000.
