Problem: Genome:

Tandem repeats are usually caused by slippage during replication, unequal crossing-over and gene conversion, satellite DNA and microsatellites are forms of tandem repeats in the genome. Although tandem repeats count for a significant proportion in genome, the largest proportion in mammalian is the other type, interspersed repeats.

What is gene conversion caused by?
---
A: unanswerable

Problem: Infection:

Serological methods are highly sensitive, specific and often extremely rapid tests used to identify microorganisms. These tests are based upon the ability of an antibody to bind specifically to an antigen. The antigen, usually a protein or carbohydrate made by an infectious agent, is bound by the antibody. This binding then sets off a chain of events that can be visibly obvious in various ways, dependent upon the test. For example, "Strep throat" is often diagnosed within minutes, and is based on the appearance of antigens made by the causative agent, S. pyogenes, that is retrieved from a patients throat with a cotton swab. Serological tests, if available, are usually the preferred route of identification, however the tests are costly to develop and the reagents used in the test often require refrigeration. Some serological methods are extremely costly, although when commonly used, such as with the "strep test", they can be inexpensive.

What is the antigen bound to by the antibody usually?
---
A: a protein or carbohydrate made by an infectious agent

Problem: Capacitor:

Charles Pollak (born Karol Pollak), the inventor of the first electrolytic capacitors, found out that the oxide layer on an aluminum anode remained stable in a neutral or alkaline electrolyte, even when the power was switched off. In 1896 he filed a patent for an "Electric liquid capacitor with aluminum electrodes." Solid electrolyte tantalum capacitors were invented by Bell Laboratories in the early 1950s as a miniaturized and more reliable low-voltage support capacitor to complement their newly invented transistor.

Why did Bell labs create their new type of capacitor?
---
A: to complement their newly invented transistor

Problem: Charleston, South Carolina:

After Charles II of England (16301685) was restored to the English throne in 1660 following Oliver Cromwell's Protectorate, he granted the chartered Province of Carolina to eight of his loyal friends, known as the Lords Proprietors, on March 24, 1663. It took seven years before the group arranged for settlement expeditions. The first of these founded Charles Town, in 1670. Governance, settlement, and development were to follow a visionary plan known as the Grand Model prepared for the Lords Proprietors by John Locke.

What was the plan to settle and develop the Province of Carolina?
---
A:
the Grand Model
