Here is a question about this article: The Desert National Park in Jaisalmer is spread over an area of 3,162 square kilometres (1,221 sq mi), is an excellent example of the ecosystem of the Thar Desert and its diverse fauna. Seashells and massive fossilised tree trunks in this park record the geological history of the desert. The region is a haven for migratory and resident birds of the desert. One can see many eagles, harriers, falcons, buzzards, kestrels and vultures. Short-toed eagles (Circaetus gallicus), tawny eagles (Aquila rapax), spotted eagles (Aquila clanga), laggar falcons (Falco jugger) and kestrels are the commonest of these.

The problem: Answer a question about this article:
Geology did not undergo systematic restructuring during the Scientific Revolution, but individual theorists made important contributions. Robert Hooke, for example, formulated a theory of earthquakes, and Nicholas Steno developed the theory of superposition and argued that fossils were the remains of once-living creatures. Beginning with Thomas Burnet's Sacred Theory of the Earth in 1681, natural philosophers began to explore the idea that the Earth had changed over time. Burnet and his contemporaries interpreted Earth's past in terms of events described in the Bible, but their work laid the intellectual foundations for secular interpretations of Earth history.
What theory did Nicholas Steno discover?
****
The answer: the theory of superposition


Problem: Please answer a question about the following article about Annelid:
Traditionally the annelids have been divided into two major groups, the polychaetes and clitellates. In turn the clitellates were divided into oligochaetes, which include earthworms, and hirudinomorphs, whose best-known members are leeches. For many years there was no clear arrangement of the approximately 80 polychaete families into higher-level groups. In 1997 Greg Rouse and Kristian Fauchald attempted a "first heuristic step in terms of bringing polychaete systematics to an acceptable level of rigour", based on anatomical structures, and divided polychaetes into:
How many polychaete families are there?
A: approximately 80


Question: Read this and answer the question

After a death sentence is affirmed in state collateral review, the prisoner may file for federal habeas corpus, which is a unique type of lawsuit that can be brought in federal courts. Federal habeas corpus is a species of collateral review, and it is the only way that state prisoners may attack a death sentence in federal court (other than petitions for certiorari to the United States Supreme Court after both direct review and state collateral review). The scope of federal habeas corpus is governed by the Antiterrorism and Effective Death Penalty Act of 1996, which restricted significantly its previous scope. The purpose of federal habeas corpus is to ensure that state courts, through the process of direct review and state collateral review, have done at least a reasonable job in protecting the prisoner's federal constitutional rights. Prisoners may also use federal habeas corpus suits to bring forth new evidence that they are innocent of the crime, though to be a valid defense at this late stage in the process, evidence of innocence must be truly compelling.

What act restricted the scope of federal habeas corpus?
Answer: the Antiterrorism and Effective Death Penalty Act of 1996


In September 1828 Chopin, while still a student, visited Berlin with a family friend, zoologist Feliks Jarocki, enjoying operas directed by Gaspare Spontini and attending concerts by Carl Friedrich Zelter, Felix Mendelssohn and other celebrities. On an 1829 return trip to Berlin, he was a guest of Prince Antoni Radziwiłł, governor of the Grand Duchy of Posen—himself an accomplished composer and aspiring cellist. For the prince and his pianist daughter Wanda, he composed his Introduction and Polonaise brillante in C major for cello and piano, Op. 3.
Who was Frédéric a guest of during his stay in Berlin in 1829?
Prince Antoni Radziwiłł
