Problem: Please answer a question about the following article about Database:
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).
What are huge quantities of information stored as?
A: bits
Problem: Please answer a question about the following article about Insect:
Many of these species have adaptations to help in under-water locomotion. Water beetles and water bugs have legs adapted into paddle-like structures. Dragonfly naiads use jet propulsion, forcibly expelling water out of their rectal chamber. Some species like the water striders are capable of walking on the surface of water. They can do this because their claws are not at the tips of the legs as in most insects, but recessed in a special groove further up the leg; this prevents the claws from piercing the water's surface film. Other insects such as the Rove beetle Stenus are known to emit pygidial gland secretions that reduce surface tension making it possible for them to move on the surface of water by Marangoni propulsion (also known by the German term Entspannungsschwimmen).
Dragonflys shoot water from where?
A: rectal chamber
Problem: Please answer a question about the following article about St. John%27s, Newfoundland and Labrador:
St. John's (/sentdnz/, local /sentdnz/) is the capital and largest city in Newfoundland and Labrador, Canada. St. John's was incorporated as a city in 1888, yet is considered by some to be the oldest English-founded city in North America. It is located on the eastern tip of the Avalon Peninsula on the island of Newfoundland. With a population of 214,285 as of July 1, 2015, the St. John's Metropolitan Area is the second largest Census Metropolitan Area (CMA) in Atlantic Canada after Halifax and the 20th largest metropolitan area in Canada. It is one of the world's top ten oceanside destinations, according to National Geographic Magazine. Its name has been attributed to the feast day of John the Baptist, when John Cabot was believed to have sailed into the harbour in 1497, and also to a Basque fishing town with the same name.
In what year did St. John's have a population of 214,285?
A: 2015
Problem: Please answer a question about the following article about Affirmative action in the United States:
Proponents of affirmative action recognize that the policy is inherently unequal; however, minding the inescapable fact that historic inequalities exist in America, they believe the policy is much more fair than one in which these circumstances are not taken into account. Furthermore, those in favor of affirmative action see it as an effort towards inclusion rather than a discriminatory practice. "Job discrimination is grounded in prejudice and exclusion, whereas affirmative action is an effort to overcome prejudicial treatment through inclusion. The most effective way to cure society of exclusionary practices is to make special efforts at inclusion, which is exactly what affirmative action does."
What is one of the issues with affirmative action?
A:
inherently unequal
