The Maurya Empire (322185 BCE) was the first empire to unify India into one state, and was the largest on the Indian subcontinent. At its greatest extent, the Mauryan Empire stretched to the north up to the natural boundaries of the Himalayas and to the east into what is now Assam. To the west, it reached beyond modern Pakistan, to the Hindu Kush mountains in what is now Afghanistan. The empire was established by Chandragupta Maurya in Magadha (in modern Bihar) when he overthrew the Nanda Dynasty. Chandragupta's son Bindusara succeeded to the throne around 297 BC. By the time he died in c. 272 BC, a large part of the subcontinent was under Mauryan suzerainty. However, the region of Kalinga (around modern day Odisha) remained outside Mauryan control, perhaps interfering with their trade with the south.
In what year did Chandraguta's son come to the throne?
A: 297 BC

Newly electrified lines often show a "sparks effect", whereby electrification in passenger rail systems leads to significant jumps in patronage / revenue. The reasons may include electric trains being seen as more modern and attractive to ride, faster and smoother service, and the fact that electrification often goes hand in hand with a general infrastructure and rolling stock overhaul / replacement, which leads to better service quality (in a way that theoretically could also be achieved by doing similar upgrades yet without electrification). Whatever the causes of the sparks effect, it is well established for numerous routes that have electrified over decades.
What is well established for routes that have been electrified for days?
A: unanswerable
