Problem: On the Origin of Species:

Chapter X examines whether patterns in the fossil record are better explained by common descent and branching evolution through natural selection, than by the individual creation of fixed species. Darwin expected species to change slowly, but not at the same rate some organisms such as Lingula were unchanged since the earliest fossils. The pace of natural selection would depend on variability and change in the environment. This distanced his theory from Lamarckian laws of inevitable progress. It has been argued that this anticipated the punctuated equilibrium hypothesis, but other scholars have preferred to emphasise Darwin's commitment to gradualism. He cited Richard Owen's findings that the earliest members of a class were a few simple and generalised species with characteristics intermediate between modern forms, and were followed by increasingly diverse and specialised forms, matching the branching of common descent from an ancestor. Patterns of extinction matched his theory, with related groups of species having a continued existence until extinction, then not reappearing. Recently extinct species were more similar to living species than those from earlier eras, and as he had seen in South America, and William Clift had shown in Australia, fossils from recent geological periods resembled species still living in the same area.

What did Darwin believe were the key things needed for variation of species to form?
---
A: variability and change in the environment

Problem: Group (mathematics):

Two groups G and H are called isomorphic if there exist group homomorphisms a: G H and b: H G, such that applying the two functions one after another in each of the two possible orders gives the identity functions of G and H. That is, a(b(h)) = h and b(a(g)) = g for any g in G and h in H. From an abstract point of view, isomorphic groups carry the same information. For example, proving that g g = 1G for some element g of G is equivalent to proving that a(g) a(g) = 1H, because applying a to the first equality yields the second, and applying b to the second gives back the first.

What similar element do isomorphic groups carry?
---
A: isomorphic groups

Problem: Digimon:

The series is set three years after the events of Digimon Adventure 02, when Digimon who turn rogue by a mysterious infection appear to wreak havoc in the Human World. Tai and the other DigiDestined from the original series reunite with their partners and start fighting back with support from the Japanese government, while Davis, Yolei, Cody and Ken are defeated by a powerful enemy called Alphamon and disappear without a trace. Tai and the others also meet another DigiDestined called Meiko Mochizuki and her partner Meicoomon who become their friends, until Meicoomon turns hostile as well and flees after an encounter with Ken, who reappears suddenly, once again as the Digimon Emperor. The film series also feature several DigiDestined having their partners Digivolve up to the Mega level for the first time, a feat only Tai and Matt had achieved previously.

Whats the name of the group that defeats Cody and Ken?
---
A: Alphamon

Problem: Universal Studios:

By the early 1940s, the company was concentrating on lower-budget productions that were the company's main staple: westerns, melodramas, serials and sequels to the studio's horror pictures, the latter now solely B pictures. The studio fostered many series: The Dead End Kids and Little Tough Guys action features and serials (193843); the comic adventures of infant Baby Sandy (193841); comedies with Hugh Herbert (193842) and The Ritz Brothers (194043); musicals with Robert Paige, Jane Frazee, The Andrews Sisters, and The Merry Macs (193845); and westerns with Tom Mix (193233), Buck Jones (193336), Bob Baker (193839), Johnny Mack Brown (193843); Rod Cameron (194445), and Kirby Grant (194647).

When did westerns with Johnny Rod Brown run?

A:
unanswerable
