Problem: Flowering plant:

The evolution of seed plants and later angiosperms appears to be the result of two distinct rounds of whole genome duplication events. These occurred at 319 million years ago and 192 million years ago. Another possible whole genome duplication event at 160 million years ago perhaps created the ancestral line that led to all modern flowering plants. That event was studied by sequencing the genome of an ancient flowering plant, Amborella trichopoda, and directly addresses Darwin's "abominable mystery."

When did the first whole genome duplication event occur?
---
A: 319 million years ago

Problem: Oklahoma:

Oklahoma had 598 incorporated places in 2010, including four cities over 100,000 in population and 43 over 10,000. Two of the fifty largest cities in the United States are located in Oklahoma, Oklahoma City and Tulsa, and 65 percent of Oklahomans live within their metropolitan areas, or spheres of economic and social influence defined by the United States Census Bureau as a metropolitan statistical area. Oklahoma City, the state's capital and largest city, had the largest metropolitan area in the state in 2010, with 1,252,987 people, and the metropolitan area of Tulsa had 937,478 residents. Between 2000 and 2010, the cities that led the state in population growth were Blanchard (172.4%), Elgin (78.2%), Jenks (77.0%), Piedmont (56.7%), Bixby (56.6%), and Owasso (56.3%).

How many incorporated cities are in Oklahoma?
---
A: 598

Problem: Hindu philosophy:

Samkhya school espouses dualism between consciousness and matter. It regards the universe as consisting of two realities; Purusa (consciousness) and prakriti (matter). Jiva (a living being) is that state in which purusa is bonded to prakriti in some form. This fusion, state the Samkhya scholars, led to the emergence of buddhi (awareness, intellect) and ahankara (individualized ego consciousness, "I-maker"). The universe is described by this school as one created by Purusa-Prakriti entities infused with various permutations and combinations of variously enumerated elements, senses, feelings, activity and mind.

What is the Samkhya school word for matter?
---
A: prakriti

Problem: Oklahoma:

Oklahoma is located in a humid subtropical region. Oklahoma lies in a transition zone between humid continental climate to the north, semi-arid climate to the west, and humid subtropical climate in the central, south and eastern portions of the state. Most of the state lies in an area known as Tornado Alley characterized by frequent interaction between cold, dry air from Canada, warm to hot, dry air from Mexico and the Southwestern U.S., and warm, moist air from the Gulf of Mexico. The interactions between these three contrasting air currents produces severe weather (severe thunderstorms, damaging thunderstorm winds, large hail and tornadoes) with a frequency virtually unseen anywhere else on planet Earth. An average 62 tornadoes strike the state per yearone of the highest rates in the world.

What is Oklahoma's main climate region?
---
A:
humid subtropical
