Problem: Literature:

In ancient India, literature originated from stories that were originally orally transmitted. Early genres included drama, fables, sutras and epic poetry. Sanskrit literature begins with the Vedas, dating back to 1500–1000 BCE, and continues with the Sanskrit Epics of Iron Age India. The Vedas are among the oldest sacred texts. The Samhitas (vedic collections) date to roughly 1500–1000 BCE, and the "circum-Vedic" texts, as well as the redaction of the Samhitas, date to c. 1000-500 BCE, resulting in a Vedic period, spanning the mid 2nd to mid 1st millennium BCE, or the Late Bronze Age and the Iron Age. The period between approximately the 6th to 1st centuries BC saw the composition and redaction of the two most influential Indian epics, the Mahabharata and the Ramayana, with subsequent redaction progressing down to the 4th century AD.

Problem: Swaziland:

Swaziland's most well-known cultural event is the annual Umhlanga Reed Dance. In the eight-day ceremony, girls cut reeds and present them to the queen mother and then dance. (There is no formal competition.) It is done in late August or early September. Only childless, unmarried girls can take part. The aims of the ceremony are to preserve girls' chastity, provide tribute labour for the Queen mother, and to encourage solidarity by working together. The royal family appoints a commoner maiden to be "induna" (captain) of the girls and she announces over the radio the dates of the ceremony. She will be an expert dancer and knowledgeable on royal protocol. One of the King's daughters will be her counterpart.

During what time of year is the Umhlanga Reed Dance?
---
A: late August or early September


Problem: Infrared:

Infrared radiation is used in industrial, scientific, and medical applications. Night-vision devices using active near-infrared illumination allow people or animals to be observed without the observer being detected. Infrared astronomy uses sensor-equipped telescopes to penetrate dusty regions of space, such as molecular clouds; detect objects such as planets, and to view highly red-shifted objects from the early days of the universe. Infrared thermal-imaging cameras are used to detect heat loss in insulated systems, to observe changing blood flow in the skin, and to detect overheating of electrical apparatus.

What discipline uses infrared telescopes to see through molecular clouds?
---
A: Infrared astronomy


Problem: Chihuahua (state):

The state has a great diversity due to the large number of microclimates found and dramatic varying terrain. The flora throughout the Sierra Madre Occidental mountain range varies with elevation. Pine (Pinus) and oak (Quercus) species are usually found at an elevation of 2,000 m (6,560 ft) above sea level. The most common species of flora found in the mountains are: Pinus, Quercus, Abies, Ficus, Vachellia, Ipomoea, Acacia, Lysiloma, Bursera, Vitex, Tabebuia, Sideroxylon, Cordia, Fouquieria, Pithecellobium. The state is home to one of the largest variation species of the genus Pinus in the world. The lower elevations have a steppe vegetation with a variety of grasses and small bushes. Several species of Juniperus dot the steppe and the transition zone.

The state has great diversity thanks to the large number of what?
---
A:
microclimates
