Context: In mid 2011, the Foundation announced in its new "Water, Sanitation, Hygiene Strategy Overview" that its funding now focuses primarily on sanitation, particularly in sub-Saharan Africa and South Asia, because access to improved sanitation is lowest in those regions. Their grant-making focus has been since 2011 on sanitation science and technology ("transformative technologies"), delivery models at scale, urban sanitation markets, building demand for sanitation, measurement and evaluation as well as policy, advocacy and communications.
A: Africa

Q: Extract the answer to the question from the following context. Question: what is the fucntion of the epidermis Context: The epidermis is typically 10 to 30 cells thick; its main function is to provide a waterproof layer. Its outermost cells are constantly lost; its bottommost cells are constantly dividing and pushing upward. The middle layer, the dermis, is 15 to 40 times thicker than the epidermis. The dermis is made up of many components, such as bony structures and blood vessels. The hypodermis is made up of adipose tissue. Its job is to store lipids, and to provide cushioning and insulation. The thickness of this layer varies widely from species to species.
A: provide a waterproof layer

Q: Extract the answer to the question from the following context. Question: How is white pine's texture? Context: If a heavy piece of pine is compared with a lightweight piece it will be seen at once that the heavier one contains a larger proportion of latewood than the other, and is therefore showing more clearly demarcated growth rings. In white pines there is not much contrast between the different parts of the ring, and as a result the wood is very uniform in texture and is easy to work. In hard pines, on the other hand, the latewood is very dense and is deep-colored, presenting a very decided contrast to the soft, straw-colored earlywood.
A: uniform

Q: Extract the answer to the question from the following context. Question: What was contained in the Ottoman libraries Context: Over the course of Ottoman history, the Ottomans managed to build a large collection of libraries complete with translations of books from other cultures, as well as original manuscripts. A great part of this desire for local and foreign manuscripts arose in the 15th Century. Sultan Mehmet II ordered Georgios Amiroutzes, a Greek scholar from Trabzon, to translate and make available to Ottoman educational institutions the geography book of Ptolemy. Another example is Ali Qushji -an astronomer, mathematician and physicist originally from Samarkand- who became a professor in two madrasas, and influenced Ottoman circles as a result of his writings and the activities of his students, even though he only spent two or three years before his death in Istanbul.
A:
translations of books from other cultures, as well as original manuscripts
