Input: Read this: New chemical glass compositions or new treatment techniques can be initially investigated in small-scale laboratory experiments. The raw materials for laboratory-scale glass melts are often different from those used in mass production because the cost factor has a low priority. In the laboratory mostly pure chemicals are used. Care must be taken that the raw materials have not reacted with moisture or other chemicals in the environment (such as alkali or alkaline earth metal oxides and hydroxides, or boron oxide), or that the impurities are quantified (loss on ignition). Evaporation losses during glass melting should be considered during the selection of the raw materials, e.g., sodium selenite may be preferred over easily evaporating SeO2. Also, more readily reacting raw materials may be preferred over relatively inert ones, such as Al(OH)3 over Al2O3. Usually, the melts are carried out in platinum crucibles to reduce contamination from the crucible material. Glass homogeneity is achieved by homogenizing the raw materials mixture (glass batch), by stirring the melt, and by crushing and re-melting the first melt. The obtained glass is usually annealed to prevent breakage during processing.
Question: What containers are used for evaporation?

Output: unanswerable

QUES: Apple's Safari had its first beta release in January 2003; as of April 2011, it had a dominant share of Apple-based web browsing, accounting for just over 7% of the entire browser market.

When did web browsers become active?
What is the answer?
ANS: unanswerable

QUES: In Why F A Hayek is a Conservative, British policy analyst Madsen Pirie claims Hayek mistakes the nature of the conservative outlook. Conservatives, he says, are not averse to change but like Hayek, they are highly averse to change being imposed on the social order by people in authority who think they know how to run things better. They wish to allow the market to function smoothly and give it the freedom to change and develop. It is an outlook, says Pirie, that Hayek and conservatives both share.
What does Pirie claim conservatives want for the free market?

ANS: to function smoothly

Another effective way to decrease the transmission rate of infectious diseases is to recognize the effects of small-world networks. In epidemics, there are often extensive interactions within hubs or groups of infected individuals and other interactions within discrete hubs of susceptible individuals. Despite the low interaction between discrete hubs, the disease can jump to and spread in a susceptible hub via a single or few interactions with an infected hub. Thus, infection rates in small-world networks can be reduced somewhat if interactions between individuals within infected hubs are eliminated (Figure 1). However, infection rates can be drastically reduced if the main focus is on the prevention of transmission jumps between hubs. The use of needle exchange programs in areas with a high density of drug users with HIV is an example of the successful implementation of this treatment method. Another example is the use of ring culling or vaccination of potentially susceptible livestock in adjacent farms to prevent the spread of the foot-and-mouth virus in 2001.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is an example of a success implementation of preventing transmission jumps?
Ah, so.. needle exchange programs in areas with a high density of drug users

Question: Though the iPod was released in 2001, its price and Mac-only compatibility caused sales to be relatively slow until 2004. The iPod line came from Apple's "digital hub" category, when the company began creating software for the growing market of personal digital devices. Digital cameras, camcorders and organizers had well-established mainstream markets, but the company found existing digital music players "big and clunky or small and useless" with user interfaces that were "unbelievably awful," so Apple decided to develop its own. As ordered by CEO Steve Jobs, Apple's hardware engineering chief Jon Rubinstein assembled a team of engineers to design the iPod line, including hardware engineers Tony Fadell and Michael Dhuey, and design engineer Sir Jonathan Ive. Rubinstein had already discovered the Toshiba disk drive when meeting with an Apple supplier in Japan, and purchased the rights to it for Apple, and had also already worked out how the screen, battery, and other key elements would work. The aesthetic was inspired by the 1958 Braun T3 transistor radio designed by Dieter Rams, while the wheel based user interface was prompted by Bang & Olufsen's BeoCom 6000 telephone. The product ("the Walkman of the twenty-first century" ) was developed in less than one year and unveiled on October 23, 2001. Jobs announced it as a Mac-compatible product with a 5 GB hard drive that put "1,000 songs in your pocket."
Try to answer this question if possible: What was the storage capacity of the first iPod?
Answer: 5 GB

Input: Read this: New Delhi is particularly renowned for its beautifully landscaped gardens that can look quite stunning in spring. The largest of these include Buddha Jayanti Park and the historic Lodi Gardens. In addition, there are the gardens in the Presidential Estate, the gardens along the Rajpath and India Gate, the gardens along Shanti Path, the Rose Garden, Nehru Park and the Railway Garden in Chanakya Puri. Also of note is the garden adjacent to the Jangpura Metro Station near the Defence Colony Flyover, as are the roundabout and neighbourhood gardens throughout the city.
Question: New Delhi is well known for what type of beautifully landscaped feature?

Output:
gardens
