Simply a glare screen, because it clearly states what it protects one against, I guess.
Answer:
b. shift from curve CD to curve EF.
Required Details of the Question:
The image of the curve required to answer the question has been attached.
Explanation:
A production possibilities curve shows various combinations of the amounts of two goods( in this case capital and consumer goods) which can be produced within the given resources and a graphical representation showing all the possible options of output for the two products that can be produced using all factors of production.
Now the growth of an economy is best illustrated in the image by the shift from curve CD to curve EF, this means that as the nation's production capacity increases, its production possibilities curve shift outward showing an increase in production of both goods.
The answer that fills in the blank is orientation. It is because orientation does not provide all the details of what they are doing but a guideline of what they must do, in order for them to be guided on the things that they need to learn as they start. They require proper guidance which is the orientation before performing before hand. Especially when they are not familiar on what they need to do.
