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 answer would be 1 & 3
1. By designating a minimum number of seats in the parliament reserved for Women, we ensure proper representation of a group that makes up more than 50% of the population.
Women political leaders will ensure that laws, rules and regulations can be developed from the point of view of women.

Explanation:
Two questions which arises in my mind about aurora borealis are:
- Why does aurora borealis occur?
- Why does aurora borealis occur in a particular time of the year?
Answers:
- As solar wind approaches the Earth, it meets the Earth's magnetic field. In the ionosphere, the ions of the solar wind collide with atoms of oxygen and nitrogen from the Earth's atmosphere. The energy released during these collisions causes aurora borealis.
- Aurora borealis is active the whole year. Since it needs to be dark in order to see aurora borealis in the sky, late August/September through the very beginning of April is the best time to go to a destination located in the aurora zone for a chance to see them.
Note: These are the questions which arises in my mind only. It may differ from person to person.
