<em>"that this nation, under God, shall have a new birth of freedom- and that government of the people, by the people, for the people, shall not perish from the earth."</em>
The focus of an interest group is to promote a specific cause or issue.
What is focus?
A focus, also known as an image point in geometrical optics, is where light rays originating from one point on the object converge. Despite being a point conceptually, the focus actually has a spatial extent known as the blur circle. The imaging optics' aberrations could be to blame for this suboptimal focusing. The Airy disc, which is brought on by diffraction from of the optical system's aperture, is the smallest blur circle that can be created in the absence of significant aberrations. The Airy circle seems to be smallest for large apertures, while aberrations tend to get worse as the aperture diameter rises. If light from object points has been converged almost to the maximum extent in the image, then the image, or image point or region, is in focus. If light is not well converged, then the image is out of focus.

Answer: Create a model.
Explanation: He should develop a model of the Earth-Moon-Sun system. This will let him clearly see how the Moon must move in order for one of its sides to always face away from the Earth. If he uses a light source for the Sun in his model, it will also show how the phases of the Moon happen. The real Earth-Moon-Sun system is too large for him to observe it in the same way.
