Problem: Hunter-gatherer:

It is easy for Western-educated scholars to fall into the trap of viewing hunter-gatherer social and sexual arrangements in the light of Western values.[editorializing] One common arrangement is the sexual division of labour, with women doing most of the gathering, while men concentrate on big game hunting. It might be imagined that this arrangement oppresses women, keeping them in the domestic sphere. However, according to some observers, hunter-gatherer women would not understand this interpretation. Since childcare is collective, with every baby having multiple mothers and male carers, the domestic sphere is not atomised or privatised but an empowering place to be.[citation needed] In all hunter-gatherer societies, women appreciate the meat brought back to camp by men. An illustrative account is Megan Biesele's study of the southern African Ju/'hoan, 'Women Like Meat'. Recent archaeological research suggests that the sexual division of labor was the fundamental organisational innovation that gave Homo sapiens the edge over the Neanderthals, allowing our ancestors to migrate from Africa and spread across the globe.

What gave the Neanderthals the edge over Homo sapiens?

Problem: In China, it opened on 12 November and earned $15 million on its opening day, which is the second biggest 2D single day gross for a Hollywood film behind the $18.5 million opening day of Mission: Impossible Rogue Nation and occupying 43% of all available screens which included $790,000 in advance night screenings. Through its opening weekend, it earned $48.1 million from 14,700 screens which is 198% ahead of Skyfall, a new record for a Hollywood 2D opening. IMAX contributed $4.6 million on 246 screens, also a new record for a three-day opening for a November release (breaking Interstellar's record). In its second weekend, it added $12.1 million falling precipitously by 75% which is the second worst second weekend drop for any major Hollywood release in China of 2015. It grossed a total of $84.7 million there after four weekends. Albeit a strong opening it failed to attain the $100 million mark as projected.
By the weekend after its China release, how much had revenue decreased?

Answer: 75%

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
While inert gas reduces filament evaporation, it also conducts heat from the filament, thereby cooling the filament and reducing efficiency. At constant pressure and temperature, the thermal conductivity of a gas depends upon the molecular weight of the gas and the cross sectional area of the gas molecules. Higher molecular weight gasses have lower thermal conductivity, because both the molecular weight is higher and also the cross sectional area is higher. Xenon gas improves efficiency because of its high molecular weight, but is also more expensive, so its use is limited to smaller lamps.
How does the molecular weight of a gas relate to thermal conductivity?
A: Higher molecular weight gasses have lower thermal conductivity

Context and question: Patronage refers to favoring supporters, for example with government employment. This may be legitimate, as when a newly elected government changes the top officials in the administration in order to effectively implement its policy. It can be seen as corruption if this means that incompetent persons, as a payment for supporting the regime, are selected before more able ones. In nondemocracies many government officials are often selected for loyalty rather than ability. They may be almost exclusively selected from a particular group (for example, Sunni Arabs in Saddam Hussein's Iraq, the nomenklatura in the Soviet Union, or the Junkers in Imperial Germany) that support the regime in return for such favors. A similar problem can also be seen in Eastern Europe, for example in Romania, where the government is often accused of patronage (when a new government comes to power it rapidly changes most of the officials in the public sector).
What country quickly changes most people working in government position when a new government comes into power?
Answer: Romania

Question: In All Life is Problem Solving, Popper sought to explain the apparent progress of scientific knowledge that is, how it is that our understanding of the universe seems to improve over time. This problem arises from his position that the truth content of our theories, even the best of them, cannot be verified by scientific testing, but can only be falsified. Again, in this context the word "falsified" does not refer to something being "fake"; rather, that something can be (i.e., is capable of being) shown to be false by observation or experiment. Some things simply do not lend themselves to being shown to be false, and therefore, are not falsifiable. If so, then how is it that the growth of science appears to result in a growth in knowledge? In Popper's view, the advance of scientific knowledge is an evolutionary process characterised by his formula:
Is there an answer to this question: Which of Popper's works addresses the improvement of scientific understanding of the world over time?

Answer: All Life is Problem Solving

Longjing tea (also called dragon well tea), originating in Hangzhou, is one of the most prestigious, if not the most prestigious Chinese tea. Hangzhou is also renowned for its silk umbrellas and hand fans. Zhejiang cuisine (itself subdivided into many traditions, including Hangzhou cuisine) is one of the eight great traditions of Chinese cuisine.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What type of clothes is Hangzhou known for?
Ah, so..
