Problem: Zinc is a chemical element with symbol Zn and atomic number 30. It is the first element of group 12 of the periodic table. In some respects zinc is chemically similar to magnesium: its ion is of similar size and its only common oxidation state is +2. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest mineable amounts are found in Australia, Asia, and the United States. Zinc production includes froth flotation of the ore, roasting, and final extraction using electricity (electrowinning).
How many stable isotopes does zinc have?
The answer is the following: five

Problem: The earliest known inscriptions in Sanskrit date to the first century BCE.[citation needed] They are in the Brahmi script, which was originally used for Prakrit, not Sanskrit. It has been described as a paradox that the first evidence of written Sanskrit occurs centuries later than that of the Prakrit languages which are its linguistic descendants. In northern India, there are Brāhmī inscriptions dating from the third century BCE onwards, the oldest appearing on the famous Prakrit pillar inscriptions of king Ashoka. The earliest South Indian inscriptions in Tamil Brahmi, written in early Tamil, belong to the same period. When Sanskrit was written down, it was first used for texts of an administrative, literary or scientific nature. The sacred texts were preserved orally, and were set down in writing "reluctantly" (according to one commentator), and at a comparatively late date.
What language is the descendant of Sanskrit?
The answer is the following: Prakrit

Problem: Scholars have debated the relationship and differences within āstika philosophies and with nāstika philosophies, starting with the writings of Indologists and Orientalists of the 18th and 19th centuries, which were themselves derived from limited availability of Indian literature and medieval doxographies. The various sibling traditions included in Hindu philosophies are diverse, and they are united by shared history and concepts, same textual resources, similar ontological and soteriological focus, and cosmology. While Buddhism and Jainism are considered distinct philosophies and religions, some heterodox traditions such as Cārvāka are often considered as distinct schools within Hindu philosophy.
What have scholars argued about with regards to nastika and astika philosophies?
The answer is the following: relationship and differences

Problem: His first professional TV job came when he was hired to direct one of the segments for the 1969 pilot episode of Night Gallery. The segment, "Eyes," starred Joan Crawford; she and Spielberg were reportedly close friends until her death. The episode is unusual in his body of work, in that the camerawork is more highly stylized than his later, more "mature" films. After this, and an episode of Marcus Welby, M.D., Spielberg got his first feature-length assignment: an episode of The Name of the Game called "L.A. 2017". This futuristic science fiction episode impressed Universal Studios and they signed him to a short contract. He did another segment on Night Gallery and did some work for shows such as Owen Marshall: Counselor at Law and The Psychiatrist, before landing the first series episode of Columbo (previous episodes were actually TV films).
What year was Spielberg hired to direct one of the segments for "Night Gallery"?
The answer is the following:
1969
