Problem: Glass:

The most familiar, and historically the oldest, types of glass are "silicate glasses" based on the chemical compound silica (silicon dioxide, or quartz), the primary constituent of sand. The term glass, in popular usage, is often used to refer only to this type of material, which is familiar from use as window glass and in glass bottles. Of the many silica-based glasses that exist, ordinary glazing and container glass is formed from a specific type called soda-lime glass, composed of approximately 75% silicon dioxide (SiO2), sodium oxide (Na2O) from sodium carbonate (Na2CO3), calcium oxide, also called lime (CaO), and several minor additives. A very clear and durable quartz glass can be made from pure silica, but the high melting point and very narrow glass transition of quartz make glassblowing and hot working difficult. In glasses like soda lime, the compounds added to quartz are used to lower the melting temperature and improve workability, at a cost in the toughness, thermal stability, and optical transmittance.

What kind of glass are containers made from?
---
A: soda-lime glass

Problem: In many societies, however, a particular dialect, often the sociolect of the elite class, comes to be identified as the "standard" or "proper" version of a language by those seeking to make a social distinction, and is contrasted with other varieties. As a result of this, in some contexts the term "dialect" refers specifically to varieties with low social status. In this secondary sense of "dialect", language varieties are often called dialects rather than languages:
With what social class it the standard dialect commonly associated?

Answer: the elite class

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The Sardinian language is considered to be its own Romance language family, separate not only from standard Italian but also the wider Italo-Dalmatian family, and it includes the Campidanese Sardinian and Logudorese Sardinian variants. However, Gallurese, Sassarese, and Corsican are also spoken in Sardinia, and these languages are considered closely related or derived from the Italian Tuscan language and thus are Italo-Dalmatian languages. Furthermore, the Gallo-Romance language of Ligurian and the Catalan Algherese dialect are also spoken in Sardinia.
Which language is considered to be it's only Sardinian language family?
A: unanswerable

Question: Today, Estonian society encourages liberty and liberalism, with popular commitment to the ideals of the limited government, discouraging centralised power and corruption. The Protestant work ethic remains a significant cultural staple, and free education is a highly prized institution. Like the mainstream culture in the other Nordic countries, Estonian culture can be seen to build upon the ascetic environmental realities and traditional livelihoods, a heritage of comparatively widespread egalitarianism out of practical reasons (see: Everyman's right and universal suffrage), and the ideals of closeness to nature and self-sufficiency (see: summer cottage).
Is there an answer to this question: What ideal does Estonia hold towards the environment?

Answer: closeness to nature

Problem: IBM:

The company originated in 1911 as the Computing-Tabulating-Recording Company (CTR) through the consolidation of The Tabulating Machine Company, the International Time Recording Company, the Computing Scale Company and the Bundy Manufacturing Company. CTR was renamed "International Business Machines" in 1924, a name which Thomas J. Watson first used for a CTR Canadian subsidiary. The initialism IBM followed. Securities analysts nicknamed the company Big Blue for its size and common use of the color in products, packaging and its logo.

What was the name of the company that eventually became IBM?
---
A:
Computing-Tabulating-Recording Company (CTR)
