Leticia is a space scientist who made this diagram of the Moon and Earth as seen from above (top view), with sunlight coming from the left, as shown by the arrows. Why does Leticia’s diagram show that it’s brighter on the left half of the Moon?

Tania went outside and made two observations of the Moon that were several days apart. Her observations are shown in the diagram above. The light part of the Moon appeared to get larger over time. Why did this happen?

The diagrams above show Earth and the Moon in different positions, as seen from above (top view). Sunlight is coming from the left, but these diagrams do not show what parts of Earth or the Moon are light or dark.
Could the half of the Moon that faces Earth ever be completely dark in any of these diagrams?

Felipe believes that whenever the Moon is in the position that is shown from above (top view) in Diagram A, the Moon always looks completely bright in the view from Earth, as shown in Diagram B.
Is Felipe correct? If he is correct, explain why the Moon always looks bright from Earth in that position, and explain how he should show light on the Moon in Diagram A. If he is incorrect, explain how else the Moon can look when it is in that position.
Written Response CFS:
Accurately identifies the position of the Moon to predict the correct Moon phase
Accurately describes the relationship between light and the appearance of illuminated objects
Accurately describes the relationship between the moons position and the appearance from Earth
