Problem: Chicago Cubs:

The Cubs had no official physical mascot prior to Clark, though a man in a 'polar bear' looking outfit, called "The Bear-man" (or Beeman), which was mildly popular with the fans, paraded the stands briefly in the early 1990s. There is no record of whether or not he was just a fan in a costume or employed by the club. Through the 2013 season, there were "Cubbie-bear" mascots outside of Wrigley on game day, but none are employed by the team. They pose for pictures with fans for tips. The most notable of these was "Billy Cub" who worked outside of the stadium until for over 6 years until July 2013, when the club asked him to stop. Billy Cub, who is played by fan John Paul Weier, had unsuccessfully petitioned the team to become the official mascot.

Who played Billy Cub?

A: John Paul Weier


Problem: The chemistry of zinc is dominated by the +2 oxidation state. When compounds in this oxidation state are formed the outer shell s electrons are lost, which yields a bare zinc ion with the electronic configuration [Ar]3d10. In aqueous solution an octahedral complex, [Zn(H
2O)6]2+ is the predominant species. The volatilization of zinc in combination with zinc chloride at temperatures above 285 °C indicates the formation of Zn
2Cl
2, a zinc compound with a +1 oxidation state. No compounds of zinc in oxidation states other than +1 or +2 are known. Calculations indicate that a zinc compound with the oxidation state of +4 is unlikely to exist.
What oxidation state dominates zinc?

Answer: +2

Every dollar ($1) that is spent on pesticides for crops yields four dollars ($4) in crops saved. This means based that, on the amount of money spent per year on pesticides, $10 billion, there is an additional $40 billion savings in crop that would be lost due to damage by insects and weeds. In general, farmers benefit from having an increase in crop yield and from being able to grow a variety of crops throughout the year. Consumers of agricultural products also benefit from being able to afford the vast quantities of produce available year-round. The general public also benefits from the use of pesticides for the control of insect-borne diseases and illnesses, such as malaria. The use of pesticides creates a large job market within the agrichemical sector.
What amount is spent annualoy on pesticides?
A: $10 billion


Context and question: Universities created by bilateral or multilateral treaties between states are intergovernmental. An example is the Academy of European Law, which offers training in European law to lawyers, judges, barristers, solicitors, in-house counsel and academics. EUCLID (Pôle Universitaire Euclide, Euclid University) is chartered as a university and umbrella organisation dedicated to sustainable development in signatory countries, and the United Nations University engages in efforts to resolve the pressing global problems that are of concern to the United Nations, its peoples and member states. The European University Institute, a post-graduate university specialised in the social sciences, is officially an intergovernmental organisation, set up by the member states of the European Union.
What type of study does the EUCUD focus on?
Answer: unanswerable


Question: Agricultural diversity can also be divided by whether it is ‘planned’ diversity or ‘associated’ diversity. This is a functional classification that we impose and not an intrinsic feature of life or diversity. Planned diversity includes the crops which a farmer has encouraged, planted or raised (e.g.: crops, covers, symbionts and livestock, among others), which can be contrasted with the associated diversity that arrives among the crops, uninvited (e.g.: herbivores, weed species and pathogens, among others).
Is there an answer to this question: What type of diversity includes the crops which a farmer has encouraged, planted or raised?

Answer: Planned diversity

In the early part of the 20th century, San Diego hosted two World's Fairs: the Panama-California Exposition in 1915 and the California Pacific International Exposition in 1935. Both expositions were held in Balboa Park, and many of the Spanish/Baroque-style buildings that were built for those expositions remain to this day as central features of the park. The buildings were intended to be temporary structures, but most remained in continuous use until they progressively fell into disrepair. Most were eventually rebuilt, using castings of the original façades to retain the architectural style. The menagerie of exotic animals featured at the 1915 exposition provided the basis for the San Diego Zoo. During the 1950s there was a citywide festival called Fiesta del Pacifico highlighting the area's Spanish and Mexican past. In the 2010s there was a proposal for a large-scale celebration of the 100th anniversary of Balboa Park, but the plans were abandoned when the organization tasked with putting on the celebration went out of business.
Which World Fair was hosted in San Diego in 1935?
A:
California Pacific International Exposition
