Problem: In June 2006, Steven Spielberg announced he would direct a scientifically accurate film about "a group of explorers who travel through a worm hole and into another dimension", from a treatment by Kip Thorne and producer Lynda Obst. In January 2007, screenwriter Jonathan Nolan met with them to discuss adapting Obst and Thorne's treatment into a narrative screenplay. The screenwriter suggested the addition of a "time element" to the treatment's basic idea, which was welcomed by Obst and Thorne. In March of that year, Paramount hired Nolan, as well as scientists from Caltech, forming a workshop to adapt the treatment under the title Interstellar. The following July, Kip Thorne said there was a push by people for him to portray himself in the film. Spielberg later abandoned Interstellar, which was eventually directed by Christopher Nolan.
When did Spielberg announce what would become 'Interstellar'?
The answer is the following: June 2006

Problem: In 1991, several manufacturers announced specifications for what would become known as MUSE LaserDisc, representing a span of almost 15 years until the feats of this HD analog optical disc system would finally be duplicated digitally by HD DVD and Blu-ray Disc. Encoded using NHK's MUSE "Hi-Vision" analogue TV system, MUSE discs would operate like standard LaserDiscs but would contain high-definition 1,125-line (1,035 visible lines) (Sony HDVS) video with a 5:3 aspect ratio. The MUSE players were also capable of playing standard NTSC format discs and are superior in performance to non-MUSE players even with these NTSC discs. The MUSE-capable players had several noteworthy advantages over standard LaserDisc players, including a red laser with a much narrower wavelength than the lasers found in standard players. The red laser was capable of reading through disc defects such as scratches and even mild disc rot that would cause most other players to stop, stutter or drop-out. Crosstalk was not an issue with MUSE discs, and the narrow wavelength of the laser allowed for the virtual elimination of crosstalk with normal discs.
In addition to scratches and rot, what other common LaserDisc issue was to be eliminated by MUSE discs?
The answer is the following: Crosstalk

Problem: Czech distinguishes three gendersmasculine, feminine, and neuterand the masculine gender is subdivided into animate and inanimate. With few exceptions, feminine nouns in the nominative case end in -a, -e, or -ost; neuter nouns in -o, -e, or -i, and masculine nouns in a consonant. Adjectives agree in gender and animacy (for masculine nouns in the accusative or genitive singular and the nominative plural) with the nouns they modify. The main effect of gender in Czech is the difference in noun and adjective declension, but other effects include past-tense verb endings: for example, delal (he did, or made); delala (she did, or made) and delalo (it did, or made).
How many genders does Czech distinguish?
The answer is the following: three

Problem: Cladistics is a technique borrowed from biology, where it was originally named phylogenetic systematics by Willi Hennig. In biology, the technique is used to determine the evolutionary relationships between different species. In its application in textual criticism, the text of a number of different manuscripts is entered into a computer, which records all the differences between them. The manuscripts are then grouped according to their shared characteristics. The difference between cladistics and more traditional forms of statistical analysis is that, rather than simply arranging the manuscripts into rough groupings according to their overall similarity, cladistics assumes that they are part of a branching family tree and uses that assumption to derive relationships between them. This makes it more like an automated approach to stemmatics. However, where there is a difference, the computer does not attempt to decide which reading is closer to the original text, and so does not indicate which branch of the tree is the "root"which manuscript tradition is closest to the original. Other types of evidence must be used for that purpose.
What is the biological basis for Cladistics?
The answer is the following:
to determine the evolutionary relationships between different species
