Answer:
Parallax would be most effective in measuring distances to stars which are close to the Earth.
Explanation:
In the experiment,
- The parallax shift would decrease as the pencil would move further away from the scientist's eye, so option 1 would be invalid.
- the size of the pencil remains constant, so option 2 would be invalid.
- the parallax shift can be observed when the pencil has objects in the background to provide relation, that is to say, the shift of the pencil when seen relative to background objects; therefore, if we assume that the pencil is a star nearby to the Earth, and the background objects are stars that are further away, then the shift of, and thus, distance to the nearby star can be easily observed.
The correct answer is - A. Mountains in Iraq and Oman.
The pressure created from the Arabian Plate pushing towards the Eurasian Plate has lifted the terrain at some parts, most notably at the territory of Iraq and Oman. The most noticeable mountains in here are the Zagros Mountains in Iraq. These mountains are of great significance for the Kurdish population that considers them as sacred mountains. The pressure also affects the terrain in Iran where the Iranian Plateau is created.
