The problem: Answer a question about this article:
Apart from residences for upper and middle class households, sanitation is insufficient in most residential areas. Private flush toilets are too expensive for virtually all residents in townships due to their water consumption and installation cost. As a result, access to improved sanitation has not increased much since independence: In Namibia's rural areas 13% of the population had more than basic sanitation, up from 8% in 1990. Many of Namibia's inhabitants have to resort to "flying toilets", plastic bags to defecate which after use are flung into the bush. The use of open areas close to residential land to urinate and defecate is very common and has been identified as a major health hazard.
Besides installation cost, why are private flush toilets too expensive for most residents in Namibia?
****
The answer: water consumption

Not all of these small streams have continuous flow year-round.
The eastern river bears the name of the Native American Tribes that once live in New Haven, what is the name?

Question: Read this and answer the question

Anthropologists maintain that hunter/gatherers don't have permanent leaders; instead, the person taking the initiative at any one time depends on the task being performed. In addition to social and economic equality in hunter-gatherer societies, there is often, though not always, sexual parity as well. Hunter-gatherers are often grouped together based on kinship and band (or tribe) membership. Postmarital residence among hunter-gatherers tends to be matrilocal, at least initially. Young mothers can enjoy childcare support from their own mothers, who continue living nearby in the same camp. The systems of kinship and descent among human hunter-gatherers were relatively flexible, although there is evidence that early human kinship in general tended to be matrilineal.

What group arrangement is usual in family authority?
Answer: matrilocal

Problem: Strasbourg also offers high-class eclecticist buildings in its very extended German district, the Neustadt, being the main memory of Wilhelmian architecture since most of the major cities in Germany proper suffered intensive damage during World War II. Streets, boulevards and avenues are homogeneous, surprisingly high (up to seven stories) and broad examples of German urban lay-out and of this architectural style that summons and mixes up five centuries of European architecture as well as Neo-Egyptian, Neo-Greek and Neo-Babylonian styles. The former imperial palace Palais du Rhin, the most political and thus heavily criticized of all German Strasbourg buildings epitomizes the grand scale and stylistic sturdiness of this period. But the two most handsome and ornate buildings of these times are the Ecole internationale des Pontonniers (the former Hohere Madchenschule, girls college) with its towers, turrets and multiple round and square angles and the Ecole des Arts decoratifs with its lavishly ornate facade of painted bricks, woodwork and majolica.
What was the former girls college called?
The answer is the following: Hohere Madchenschule

Finally, an introduced species may unintentionally injure a species that depends on the species it replaces. In Belgium, Prunus spinosa from Eastern Europe leafs much sooner than its West European counterparts, disrupting the feeding habits of the Thecla betulae butterfly (which feeds on the leaves). Introducing new species often leaves endemic and other local species unable to compete with the exotic species and unable to survive. The exotic organisms may be predators, parasites, or may simply outcompete indigenous species for nutrients, water and light.
Where does the Prunus spinosa leaf much sooner?
In Belgium
