Problem: States of Germany:

Germany is a federal republic consisting of sixteen federal states (German: Bundesland, or Land).[a] Since today's Germany was formed from an earlier collection of several states, it has a federal constitution, and the constituent states retain a measure of sovereignty. With an emphasis on geographical conditions, Berlin and Hamburg are frequently called Stadtstaaten (city-states), as is the Free Hanseatic City of Bremen, which in fact includes the cities of Bremen and Bremerhaven. The remaining 13 states are called Flachenlander (literally: area states).

How many federal states are in Stadtstaaten?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Through Victoria's reign, the gradual establishment of a modern constitutional monarchy in Britain continued. Reforms of the voting system increased the power of the House of Commons at the expense of the House of Lords and the monarch. In 1867, Walter Bagehot wrote that the monarch only retained "the right to be consulted, the right to encourage, and the right to warn". As Victoria's monarchy became more symbolic than political, it placed a strong emphasis on morality and family values, in contrast to the sexual, financial and personal scandals that had been associated with previous members of the House of Hanover and which had discredited the monarchy. The concept of the "family monarchy", with which the burgeoning middle classes could identify, was solidified.
Reforms to what system increased the power of the house fo commons?
A: the voting system

Context and question: Biodiversity, a contraction of "biological diversity," generally refers to the variety and variability of life on Earth. One of the most widely used definitions defines it in terms of the variability within species, between species, and between ecosystems. It is a measure of the variety of organisms present in different ecosystems. This can refer to genetic variation, ecosystem variation, or species variation (number of species) within an area, biome, or planet. Terrestrial biodiversity tends to be greater near the equator, which seems to be the result of the warm climate and high primary productivity. Biodiversity is not distributed evenly on Earth. It is richest in the tropics. Marine biodiversity tends to be highest along coasts in the Western Pacific, where sea surface temperature is highest and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future.
Where on Earth is biodiversity the most abundnant?
Answer: It is richest in the tropics.

Question: This narrative draws on the Nidanakatha of the Jataka tales of the Theravada, which is ascribed to Buddhaghosa in the 5th century CE. Earlier biographies such as the Buddhacarita, the Lokottaravadin Mahavastu, and the Sarvastivadin Lalitavistara Sutra, give different accounts.
