Q:

6 months day and 6 months night - Country Name?

A) Nepal	B) Tibet
C) Norway	D) Iceland

Answer & Explanation Answer: C) Norway

Explanation:

The case where there is 6 months day, and 6 months night could only happen on poles because The Earth is tilted on its axis.

The pole which is away (opposite direction of sun) from the Sun remains in complete darkness till it comes in front of the sun.

So we conclude that, countries at the poles have 6 months day, and 6 months night.

So countries close to these region have such cases like, Alaska, Antarctica, Norway etc.

Norway, the northernmost inhabited region of Europe, there is no sunset from approximately 19 April to 23 August. The extreme sites are the poles, where the sun can be continuously visible for half the year. The North Pole has midnight sun for 6 months from late March to late September.

Q:

Read the passage carefully and choose the best answer to each question out of the four alternatives.

Many plays and films have depicted the life story of Gautama Buddha, but what made the musical play The Way Across unique was its regional focus. Directed by G. Kumara Swamy, the play adapted from the book Telangana lo Buddhism focused on the enlightenment of a cursed Brahmin Bawari and his 16 curious disciples willing to understand the deeper truths of birth, death, rebirth and brotherhood.

From the impressive use of projector visuals, music and shadow-play, there was every effort to lend authenticity to the theme. Despite the play's focus on Telangana, the native essence was compromised, due to the English rendition (done for a wider reach). The lines appeared jaded with literal translations. The honest performances from the crew impacted only on a surface-level. Kiran Kumar's Bawari act and Krishna Chaitanya Joshi as Pingiya (said to have propagated Buddhism from Telangana to several regions across South India) grab your attention.

Who helped spread Buddhism to South India?

A) Bawari	B) Buddha's 16 disciples
C) Telangana Buddhists	D) Pingiya

Answer & Explanation Answer: D) Pingiya
