Problem: Hyderabad:

In the 2005 National Family Health Survey, it was reported that the city's total fertility rate is 1.8,:47 which is below the replacement rate. Only 61% of children had been provided with all basic vaccines (BCG, measles and full courses of polio and DPT), fewer than in all other surveyed cities except Meerut.:98 The infant mortality rate was 35 per 1,000 live births, and the mortality rate for children under five was 41 per 1,000 live births.:97 The survey also reported that a third of women and a quarter of men are overweight or obese, 49% of children below 5 years are anaemic, and up to 20% of children are underweight,:44, 55–56 while more than 2% of women and 3% of men suffer from diabetes.:57

What was the fertility rate of Hyderabad according to a 2005 survey?

A: 1.8


Problem: On the island of Crete, along with the lyra and the laouto (lute), the mandolin is one of the main instruments used in Cretan Music. It appeared on Crete around the time of the Venetian rule of the island. Different variants of the mandolin, such as the "mantola," were used to accompany the lyra, the violin, and the laouto. Stelios Foustalierakis reported that the mandolin and the mpoulgari were used to accompany the lyra in the beginning of the 20th century in the city of Rethimno. There are also reports that the mandolin was mostly a woman's musical instrument. Nowadays it is played mainly as a solo instrument in personal and family events on the Ionian islands and Crete.
When did the mandolin appears on Crete?
---
Answer: around the time of the Venetian rule of the island.

Some topological spaces may be endowed with a group law. In order for the group law and the topology to interweave well, the group operations must be continuous functions, that is, g • h, and g−1 must not vary wildly if g and h vary only little. Such groups are called topological groups, and they are the group objects in the category of topological spaces. The most basic examples are the reals R under addition, (R ∖ {0}, ·), and similarly with any other topological field such as the complex numbers or p-adic numbers. All of these groups are locally compact, so they have Haar measures and can be studied via harmonic analysis. The former offer an abstract formalism of invariant integrals. Invariance means, in the case of real numbers for example:
What variables do locally compact groups share that can be studied by harmonic analysis?
A: Haar measures


Context and question: Downtown Miami is home to the largest concentration of international banks in the United States, and many large national and international companies. The Civic Center is a major center for hospitals, research institutes, medical centers, and biotechnology industries. For more than two decades, the Port of Miami, known as the "Cruise Capital of the World", has been the number one cruise passenger port in the world. It accommodates some of the world's largest cruise ships and operations, and is the busiest port in both passenger traffic and cruise lines.
Along with cruise lines, in what traffic does Miami's port rank first?
Answer: passenger


Question: New Haven Harbor is home to the Port of New Haven, a deep-water seaport with three berths capable of hosting vessels and barges as well as the facilities required to handle break bulk cargo. The port has the capacity to load 200 trucks a day from the ground or via loading docks. Rail transportation access is available, with a private switch engine for yard movements and private siding for loading and unloading. Approximately 400,000 square feet (40,000 m2) of inside storage and 50 acres (200,000 m2) of outside storage are available at the site. Five shore cranes with a 250-ton capacity and 26 forklifts, each with a 26-ton capacity, are also available.
Is there an answer to this question: Approximately how many square feet of interior storage is available at the Port of New Haven?

Answer: 400,000

In many situations it is desirable to consider two group elements the same if they differ by an element of a given subgroup. For example, in D4 above, once a reflection is performed, the square never gets back to the r2 configuration by just applying the rotation operations (and no further reflections), i.e. the rotation operations are irrelevant to the question whether a reflection has been performed. Cosets are used to formalize this insight: a subgroup H defines left and right cosets, which can be thought of as translations of H by arbitrary group elements g. In symbolic terms, the left and right cosets of H containing g are
When are rotation operations considered?
A:
unanswerable
