Final answer:
To increase production from point b to point d, Alpha could leverage an increase in resources or an improvement in technology, which would shift the supply curve rightward, representing higher output levels.
Step-by-step explanation:
In order for Alpha to increase production from point b to point d, several things could occur, such as an increase in resources, a change in technology, or an improvement in product quality. Specifically, an improvement in technology that reduces the cost of production can lead to a higher level of output at the same prices, represented as a rightward shift in the supply curve. Similarly, an increase in the availability or efficiency of resources can lead to increased production capabilities. On the other hand, a change that is not aligned with increasing production, such as a decrease in efficiency, would not enable Alpha to make this shift.
