Problem: Extract the answer to the question from the following context. Question: What formation is created in each bundle seperating the xylem and phloem Context: In the dicotyledons, the bundles in the very young stem are arranged in an open ring, separating a central pith from an outer cortex. In each bundle, separating the xylem and phloem, is a layer of meristem or active formative tissue known as cambium. By the formation of a layer of cambium between the bundles (interfascicular cambium), a complete ring is formed, and a regular periodical increase in thickness results from the development of xylem on the inside and phloem on the outside. The soft phloem becomes crushed, but the hard wood persists and forms the bulk of the stem and branches of the woody perennial. Owing to differences in the character of the elements produced at the beginning and end of the season, the wood is marked out in transverse section into concentric rings, one for each season of growth, called annual rings.

A: a layer of meristem or active formative tissue

Question: how many maquiladoras are in the chihuahua industrial parks Context: During the 1990s after NAFTA was signed, industrial development grew rapidly with foreign investment. Large factories known as maquiladoras were built to export manufactured goods to the United States and Canada. Today, most of the maquiladoras produce electronics, automobile, and aerospace components. There are more than 406 companies operating under the federal IMMEX or Prosec program in Chihuahua. The large portion of the manufacturing sector of the state is 425 factories divided into 25 industrial parks accounting for 12.47% of the maquiladoras in Mexico, which employ 294,026 people in the state. While export-driven manufacturing is one of the most important components of the state's economy, the industrial sector is quite diverse and can be broken down into several sectors, which are: electronics, agro-industrial, wood base manufacturing, mineral, and biotech. Similar to the rest of the country, small businesses continue to be the foundation of the state's economy. Small business employs the largest portion of the population.[citation needed]

A: 425

Problem: Extract the answer to the question from the following context. Question: What are the origins of Drama? Context: Greek drama exemplifies the earliest form of drama of which we have substantial knowledge. Tragedy, as a dramatic genre, developed as a performance associated with religious and civic festivals, typically enacting or developing upon well-known historical or mythological themes. Tragedies generally presented very serious themes. With the advent of newer technologies, scripts written for non-stage media have been added to this form. War of the Worlds (radio) in 1938 saw the advent of literature written for radio broadcast, and many works of Drama have been adapted for film or television. Conversely, television, film, and radio literature have been adapted to printed or electronic media.

A: Greek drama

Problem: Extract the answer to the question from the following context. Question: What is learned from metadata? Context: Database storage is the container of the physical materialization of a database. It comprises the internal (physical) level in the database architecture. It also contains all the information needed (e.g., metadata, "data about the data", and internal data structures) to reconstruct the conceptual level and external level from the internal level when needed. Putting data into permanent storage is generally the responsibility of the database engine a.k.a. "storage engine". Though typically accessed by a DBMS through the underlying operating system (and often utilizing the operating systems' file systems as intermediates for storage layout), storage properties and configuration setting are extremely important for the efficient operation of the DBMS, and thus are closely maintained by database administrators. A DBMS, while in operation, always has its database residing in several types of storage (e.g., memory and external storage). The database data and the additional needed information, possibly in very large amounts, are coded into bits. Data typically reside in the storage in structures that look completely different from the way the data look in the conceptual and external levels, but in ways that attempt to optimize (the best possible) these levels' reconstruction when needed by users and programs, as well as for computing additional types of needed information from the data (e.g., when querying the database).

A:
data about the data
