The most significant event between the 7th and 11th century was the Tripartite struggle centered on Kannauj that lasted for more than two centuries between the Pala Empire, Rashtrakuta Empire, and Gurjara Pratihara Empire. Southern India was ruled by the Chalukya, Chola, Pallava, Chera, Pandyan, and Western Chalukya Empires. The seventh century also saw the advent of Islam as a political power, though as a fringe, in the western part of the subcontinent, in modern-day Pakistan. The Chola dynasty conquered southern India and successfully invaded parts of Southeast Asia, Sri Lanka, Maldives and Bengal in the 11th century. The early medieval period Indian mathematics influenced the development of mathematics and astronomy in the Arab world and the Hindu numerals were introduced.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When did Islam begin to become a political power in India?
Ah, so.. seventh century

During the last three minutes of a half, the penalty for failure to place the ball in play within the 20-second play clock, known as "time count" (this foul is known as "delay of game" in American football), is dramatically different from during the first 27 minutes. Instead of the penalty being 5 yards with the down repeated, the base penalty (except during convert attempts) becomes loss of down on first or second down, and 10 yards on third down with the down repeated. In addition, as noted previously, the referee can give possession to the defence for repeated deliberate time count violations on third down.

Ah, so.. unanswerable

In any case, Alexander's toppling of the Achaemenid Empire, after his victories at the battles of the Granicus, Issus and Gaugamela, and his advance as far as modern-day Pakistan and Tajikistan, provided an important outlet for Greek culture, via the creation of colonies and trade routes along the way. While the Alexandrian empire did not survive its creator's death intact, the cultural implications of the spread of Hellenism across much of the Middle East and Asia were to prove long lived as Greek became the lingua franca, a position it retained even in Roman times. Many Greeks settled in Hellenistic cities like Alexandria, Antioch and Seleucia. Two thousand years later, there are still communities in Pakistan and Afghanistan, like the Kalash, who claim to be descended from Greek settlers.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Are any relatives of the first people of  the Grecian world still around ?
Ah, so..
