Problem: Spectre (2015 film):

Christoph Waltz was cast in the role of Franz Oberhauser, though he refused to comment on the nature of the part. It was later revealed with the film's release that he is Ernst Stavro Blofeld. Dave Bautista was cast as Mr. Hinx after producers sought an actor with a background in contact sports. After casting Berenice Lim Marlohe, a relative newcomer, as Severine in Skyfall, Mendes consciously sought out a more experienced actor for the role of Madeleine Swann, ultimately casting Lea Seydoux in the role. Monica Bellucci joined the cast as Lucia Sciarra, becoming, at the age of fifty, the oldest actress to be cast as a Bond girl. In a separate interview with Danish website Euroman, Jesper Christensen revealed he would be reprising his role as Mr. White from Casino Royale and Quantum of Solace. Christensen's character was reportedly killed off in a scene intended to be used as an epilogue to Quantum of Solace, before it was removed from the final cut of the film, enabling his return in Spectre.

A: Franz Oberhauser

Problem: Chemical communications in animals rely on a variety of aspects including taste and smell. Chemoreception is the physiological response of a sense organ (i.e. taste or smell) to a chemical stimulus where the chemicals act as signals to regulate the state or activity of a cell. A semiochemical is a message-carrying chemical that is meant to attract, repel, and convey information. Types of semiochemicals include pheromones and kairomones. One example is the butterfly Phengaris arion which uses chemical signals as a form of mimicry to aid in predation.
Chemical stimuli are signals that regulate the activity of what?

Answer: a cell

Feynman devoted the latter half of his book What Do You Care What Other People Think? to his experience on the Rogers Commission, straying from his usual convention of brief, light-hearted anecdotes to deliver an extended and sober narrative. Feynman's account reveals a disconnect between NASA's engineers and executives that was far more striking than he expected. His interviews of NASA's high-ranking managers revealed startling misunderstandings of elementary concepts. For instance, NASA managers claimed that there was a 1 in 100,000 chance of a catastrophic failure aboard the shuttle, but Feynman discovered that NASA's own engineers estimated the chance of a catastrophe at closer to 1 in 200. He concluded that the space shuttle reliability estimate by NASA management was fantastically unrealistic, and he was particularly angered that NASA used these figures to recruit Christa McAuliffe into the Teacher-in-Space program. He warned in his appendix to the commission's report (which was included only after he threatened not to sign the report), "For a successful technology, reality must take precedence over public relations, for nature cannot be fooled."
Who did NASA recruit while using accurate safety numbers?
A: unanswerable

Context and question: Videophone calls (also: videocalls, video chat as well as Skype and Skyping in verb form), differ from videoconferencing in that they expect to serve individuals, not groups. However that distinction has become increasingly blurred with technology improvements such as increased bandwidth and sophisticated software clients that can allow for multiple parties on a call. In general everyday usage the term videoconferencing is now frequently used instead of videocall for point-to-point calls between two units. Both videophone calls and videoconferencing are also now commonly referred to as a video link.
How does increased bandwidth differ from point-to-point calls?
Answer: unanswerable

Question: Symmetry groups are groups consisting of symmetries of given mathematical objectsbe they of geometric nature, such as the introductory symmetry group of the square, or of algebraic nature, such as polynomial equations and their solutions. Conceptually, group theory can be thought of as the study of symmetry.t["] Symmetries in mathematics greatly simplify the study of geometrical or analytical objects. A group is said to act on another mathematical object X if every group element performs some operation on X compatibly to the group law. In the rightmost example below, an element of order 7 of the (2,3,7) triangle group acts on the tiling by permuting the highlighted warped triangles (and the other ones, too). By a group action, the group pattern is connected to the structure of the object being acted on.
Is there an answer to this question: What does group action do to the tiling?

Answer: unanswerable

On 7 April 1963, the country changed its official name to the Socialist Federal Republic of Yugoslavia. Reforms encouraged private enterprise and greatly relaxed restrictions on freedom of speech and religious expression. Tito subsequently went on a tour of the Americas. In Chile, two government ministers resigned over his visit to that country. In the autumn of 1960 Tito met President Dwight D. Eisenhower at the United Nations General Assembly meeting. Tito and Eisenhower discussed a range of issues from arms control to economic development. When Eisenhower remarked that Yugoslavia's neutralism was "neutral on his side", Tito replied that neutralism did not imply passivity but meant "not taking sides".
Who said that neutralism did not imply passivity but mean "not taking sides"?
A:
Tito
