The statement that Phenolphthalein is not
affected by PH is False
Phenolphthalein is a colorless
chemical compound, when added to alkaline
solutions it will turns pink, which means it
has been affected by the PH.
Phenolphthalein will remain colorless
if in acidic solution, that's less than PH of 7.

Given the above production possibility curve:
- Kate has an absolute advantage in neither goods
- Sarah has the absolute advantage in both goods.
<h3>What is absolute advantage?</h3>
This is the ability of one person or group to do a certain economic activity more effectively than another person or group.
<h3>How do we arrive at the above answer?</h3>
From the PPC curves of both manufacturers, the attached schedule of production which shows how they use 8 hours of labor indicates that:
Kate produces 4 loaves of bread or 8 pieces of cake; while
Sarah produces 12 loaves or 9 pieces of cake.
Given the definition of Absolute Advantage above, it is thus correct to state that:
- Kate has an absolute advantage in neither goods: while
- Sarah has the absolute advantage in both goods.
