Ans: (c)

Explanation:

• The most common agents used in “cold rain” or snowpack augmentation cloud seeding projects are silver iodide and dry ice (frozen carbon dioxide). Other agents like liquefied gases (liquid nitrogen for example) can be used to seed clouds
• These iodide particles rise into the clouds, cause moisture to freeze. These particles act as a base for water vapours to settle on that later crystallises and falls as rain or snow.
• It is not fool proof as seeded clouds may actually travel to another location and do not cause precipitation on the intended location.
• Moreover, there are environmental consequences of spreading of harmful chemicals in atmosphere. It is also very expensive technique. If it is not controlled properly, it may result in undesirable weather conditions like flooding, hail, storms, etc.

Ans: (d)

Explanation:

• In ancient times, people used to determine directions during the night with the help of stars. The North Star (Pole star) indicates the north direction. It always remains in the same position in the sky. You should see this link to understand how we can measure it http://study.com/academy/lesson/using-the-sun-stars-to-determine-latitude-longitude.html
• Latitude is basically the angle of your place from the centre of the Earth (equatorial position).
• Option-A: would have been helpful if you had been captivated in the Northern hemisphere. Pole star is not visible from Southern hemisphere (Australia),
• Options B and C will remain constant irrespective of the position from where you measure these values. So, you cannot determine your latitude by these values. Hence it is of no use to you. None of the given options A, B or C is correct.
