Problem: Sumer:

The Sumerians were a non-Semitic caucasoid people, and spoke a language isolate; a number of linguists believed they could detect a substrate language beneath Sumerian, because names of some of Sumer's major cities are not Sumerian, revealing influences of earlier inhabitants. However, the archaeological record shows clear uninterrupted cultural continuity from the time of the early Ubaid period (5300 – 4700 BC C-14) settlements in southern Mesopotamia. The Sumerian people who settled here farmed the lands in this region that were made fertile by silt deposited by the Tigris and the Euphrates rivers.

When were settlements started in southern Mesopotamia?
---
A: early Ubaid period


Problem: Samkhya school espouses dualism between consciousness and matter. It regards the universe as consisting of two realities; Puruṣa (consciousness) and prakriti (matter). Jiva (a living being) is that state in which puruṣa 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?

Answer: prakriti


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Together with caesium and gold (both yellow), and osmium (bluish), copper is one of only four elemental metals with a natural color other than gray or silver. Pure copper is orange-red and acquires a reddish tarnish when exposed to air. The characteristic color of copper results from the electronic transitions between the filled 3d and half-empty 4s atomic shells – the energy difference between these shells is such that it corresponds to orange light. The same mechanism accounts for the yellow color of gold and caesium.
What color is fake copper?
A: unanswerable


Context and question: The Crimean War also saw the first tactical use of railways and other modern inventions, such as the electric telegraph, with the first "live" war reporting to The Times by William Howard Russell. Some credit Russell with prompting the resignation of the sitting British government through his reporting of the lacklustre condition of British forces deployed in Crimea. Additionally, the telegraph reduced the independence of British overseas possessions from their commanders in London due to such rapid communications. Newspaper readership informed public opinion in the United Kingdom and France as never before. It was the first European war to be photographed.
What reduced the independence of British overseas possessions from their commanders in London?
Answer: the telegraph


Question: The original USB 1.0 specification, which was introduced in January 1996, defined data transfer rates of 1.5 Mbit/s "Low Speed" and 12 Mbit/s "Full Speed". Microsoft Windows 95, OSR 2.1 provided OEM support for the devices. The first widely used version of USB was 1.1, which was released in September 1998. The 12 Mbit/s data rate was intended for higher-speed devices such as disk drives, and the lower 1.5 Mbit/s rate for low data rate devices such as joysticks. Apple Inc.'s iMac was the first mainstream product with USB and the iMac's success popularized USB itself. Following Apple's design decision to remove all legacy ports from the iMac, many PC manufacturers began building legacy-free PCs, which led to the broader PC market using USB as a standard.
Is there an answer to this question: 1.1 was the first widely used version of what?

Answer: USB


QUES: Many hunter-gatherers consciously manipulate the landscape through cutting or burning undesirable plants while encouraging desirable ones, some even going to the extent of slash-and-burn to create habitat for game animals. These activities are on an entirely different scale to those associated with agriculture, but they are nevertheless domestication on some level. Today, almost all hunter-gatherers depend to some extent upon domesticated food sources either produced part-time or traded for products acquired in the wild.

What technique do they use to make animal habitats?
What is the answer?
ANS:
slash-and-burn
