Problem: Please answer a question about the following article about History of India:
The Kuru kingdom was the first state-level society of the Vedic period, corresponding to the beginning of the Iron Age in northwestern India, around 1200 800 BCE, as well as with the composition of the Atharvaveda (the first Indian text to mention iron, as syama ayas, literally "black metal"). The Kuru state organized the Vedic hymns into collections, and developed the orthodox srauta ritual to uphold the social order. When the Kuru kingdom declined, the center of Vedic culture shifted to their eastern neighbours, the Panchala kingdom. The archaeological Painted Grey Ware culture, which flourished in the Haryana and western Uttar Pradesh regions of northern India from about 1100 to 600 BCE, is believed to correspond to the Kuru and Panchala kingdoms.
At the beginning of what age are the dates of the Kuru kingdom?
A: Iron Age

Problem: Please answer a question about the following article about Antarctica:
There is some evidence, in the form of ice cores drilled to about 400 m (1,300 ft) above the water line, that Lake Vostok's waters may contain microbial life. The frozen surface of the lake shares similarities with Jupiter's moon, Europa. If life is discovered in Lake Vostok, it would strengthen the argument for the possibility of life on Europa. On 7 February 2008, a NASA team embarked on a mission to Lake Untersee, searching for extremophiles in its highly alkaline waters. If found, these resilient creatures could further bolster the argument for extraterrestrial life in extremely cold, methane-rich environments.
What lake is thought to contain microbial life?
A: Lake Vostok
