Okay, so let's look at the graph.
00:03
Part a say that the movement from point a to point b shows effects of technology change.
00:09
But as we can see from point a to point b is a movement along the same production curve.
00:15
And on the same production curve, the technology is fixed.
00:19
So that means part a is false.
00:23
Reason why it is force is a and b are on the same production curve.
00:27
So on the same production curve, they have the same technology.
00:32
The only difference between a and b is the movement from a to b means an increase in capital power worked.
00:41
As a result, there is an increase in real gdp power world.
00:45
So a is false.
00:47
And let's look at b.
00:49
We say that the economy can move from point b to point c only if there's no diminishing return to capital.
00:56
So we can see that from point b to c is actually result in the production curve shift, upper shift.
01:08
So that means there's new technology that is applied to the economy as a result with a given 160 capital power worth.
01:18
The real gdp increase from 65 to 75 power worth.
01:23
Okay...
