Input: Read this: The HMWSSB regulates rainwater harvesting, sewerage services and water supply, which is sourced from several dams located in the suburbs. In 2005, the HMWSSB started operating a 116-kilometre-long (72 mi) water supply pipeline from Nagarjuna Sagar Dam to meet increasing demand. The Telangana Southern Power Distribution Company Limited manages electricity supply. As of October 2014, there were 15 fire stations in the city, operated by the Telangana State Disaster and Fire Response Department. The government-owned India Post has five head post offices and many sub-post offices in Hyderabad, which are complemented by private courier services.
Question: Which entity is responsible for the fire stations in Hyderabad?

QUES: Glass has the ability to refract, reflect, and transmit light following geometrical optics, without scattering it. It is used in the manufacture of lenses and windows. Common glass has a refraction index around 1.5. This may be modified by adding low-density materials such as boron, which lowers the index of refraction (see crown glass), or increased (to as much as 1.8) with high-density materials such as (classically) lead oxide (see flint glass and lead glass), or in modern uses, less toxic oxides of zirconium, titanium, or barium. These high-index glasses (inaccurately known as "crystal" when used in glass vessels) cause more chromatic dispersion of light, and are prized for their diamond-like optical properties.

What is a toxic additive that increases refraction?
What is the answer?
ANS: lead oxide

Phonology is a branch of linguistics concerned with the systematic organization of sounds in languages. It has traditionally focused largely on the study of the systems of phonemes in particular languages (and therefore used to be also called phonemics, or phonematics), but it may also cover any linguistic analysis either at a level beneath the word (including syllable, onset and rime, articulatory gestures, articulatory features, mora, etc.) or at all levels of language where sound is considered to be structured for conveying linguistic meaning. Phonology also includes the study of equivalent organizational systems in sign languages.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is a branch of levels?
Ah, so.. unanswerable


Question: Alaska's economy depends heavily on increasingly expensive diesel fuel for heating, transportation, electric power and light. Though wind and hydroelectric power are abundant and underdeveloped, proposals for statewide energy systems (e.g. with special low-cost electric interties) were judged uneconomical (at the time of the report, 2001) due to low (less than 50¢/gal) fuel prices, long distances and low population. The cost of a gallon of gas in urban Alaska today is usually 30–60¢ higher than the national average; prices in rural areas are generally significantly higher but vary widely depending on transportation costs, seasonal usage peaks, nearby petroleum development infrastructure and many other factors.
Try to answer this question if possible: What are some reasons why gas prices may vary in Alaska, especially?
Answer: transportation costs, seasonal usage peaks, nearby petroleum development infrastructure


Question: Video games are playable on various versions of iPods. The original iPod had the game Brick (originally invented by Apple's co-founder Steve Wozniak) included as an easter egg hidden feature; later firmware versions added it as a menu option. Later revisions of the iPod added three more games: Parachute, Solitaire, and Music Quiz.
Try to answer this question if possible: What was included on the first iPod?
Answer:
Brick
