Question: 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.
Is there an answer to this question: What do hunter-gathers intentionally manipulate?

Answer: the landscape

Question: About 98% of Antarctica is covered by the Antarctic ice sheet, a sheet of ice averaging at least 1.6 km (1.0 mi) thick. The continent has about 90% of the world's ice (and thereby about 70% of the world's fresh water). If all of this ice were melted, sea levels would rise about 60 m (200 ft). In most of the interior of the continent, precipitation is very low, down to 20 mm (0.8 in) per year; in a few "blue ice" areas precipitation is lower than mass loss by sublimation and so the local mass balance is negative. In the dry valleys, the same effect occurs over a rock base, leading to a desiccated landscape.
Is there an answer to this question: How thick is the ice that covers Antarctica?

Answer: 1.6 km

Question: Neptune has a planetary ring system, though one much less substantial than that of Saturn. The rings may consist of ice particles coated with silicates or carbon-based material, which most likely gives them a reddish hue. The three main rings are the narrow Adams Ring, 63,000 km from the centre of Neptune, the Le Verrier Ring, at 53,000 km, and the broader, fainter Galle Ring, at 42,000 km. A faint outward extension to the Le Verrier Ring has been named Lassell; it is bounded at its outer edge by the Arago Ring at 57,000 km.
Is there an answer to this question: Where is the La Verrier ring from the center of Neptune?

Answer: 53,000 km

Question: In reaction to the emergence of Reform Judaism, a group of traditionalist German Jews emerged in support of some of the values of the Haskalah, but also wanted to defend the classic, traditional interpretation of Jewish law and tradition. This group was led by those who opposed the establishment of a new temple in Hamburg , as reflected in the booklet "Ele Divrei HaBerit". As a group of Reform Rabbis convened in Braunschweig, Rabbi Jacob Ettlinger of Altona published a manifesto entitled "Shlomei Emunei Yisrael" in German and Hebrew, having 177 Rabbis sign on. At this time the first Orthodox Jewish periodical, "Der Treue Zions Waechter", was launched with the Hebrew supplement "Shomer Zion HaNe'eman" [1845 - 1855]. In later years it was Rav Ettlinger's students Rabbi Samson Raphael Hirsch and Rabbi Azriel Hildesheimer of Berlin who deepened the awareness and strength of Orthodox Jewry. Rabbi Samson Raphael Hirsch commented in 1854:
