Q: Extract the answer to the question from the following context. Question: What is one method of handling contagious diseases that is not usually done with other infectious diseases? Context: Infectious diseases are sometimes called contagious disease when they are easily transmitted by contact with an ill person or their secretions (e.g., influenza). Thus, a contagious disease is a subset of infectious disease that is especially infective or easily transmitted. Other types of infectious/transmissible/communicable diseases with more specialized routes of infection, such as vector transmission or sexual transmission, are usually not regarded as "contagious", and often do not require medical isolation (sometimes loosely called quarantine) of victims. However, this specialized connotation of the word "contagious" and "contagious disease" (easy transmissibility) is not always respected in popular use.
A: medical isolation

Q: Extract the answer to the question from the following context. Question: Glass with high density materials are sometimes called? Context: Glass has the ability to refract, reflect, and transmit light following geometrical optics, without scattering it. It is used in the manufacture of lenses and windows. Common glass has a refraction index around 1.5. This may be modified by adding low-density materials such as boron, which lowers the index of refraction (see crown glass), or increased (to as much as 1.8) with high-density materials such as (classically) lead oxide (see flint glass and lead glass), or in modern uses, less toxic oxides of zirconium, titanium, or barium. These high-index glasses (inaccurately known as "crystal" when used in glass vessels) cause more chromatic dispersion of light, and are prized for their diamond-like optical properties.
A: crystal

Q: Extract the answer to the question from the following context. Question: What is the first event that caused Jews to move? Context: By the 1st century, Babylonia, to which Jews migrated to after the Babylonian conquest as well as after the Bar Kokhba revolt in 135 CE, already held a speedily growing population of an estimated 1,000,000 Jews, which increased to an estimated 2 million  between the years 200 CE – 500 CE, both by natural growth and by immigration of more Jews from the Land of Israel, making up about 1/6 of the world Jewish population at that era. At times conversion has accounted for a part of Jewish population growth. Some have claimed that in the 1st century of the Christian era, for example, the population more than doubled, from four to 8–10 million within the confines of the Roman Empire, in good part as a result of a wave of conversion.
A: the Babylonian conquest

Q: Extract the answer to the question from the following context. Question: What location does Interstate 24 begin? Context: Interstate 40 crosses the state in a west-east orientation. Its branch interstate highways include I-240 in Memphis; I-440 in Nashville; I-140 from Knoxville to Alcoa and I-640 in Knoxville. I-26, although technically an east-west interstate, runs from the North Carolina border below Johnson City to its terminus at Kingsport. I-24 is an east-west interstate that runs cross-state from Chattanooga to Clarksville. In a north-south orientation are highways I-55, I-65, I-75, and I-81. Interstate 65 crosses the state through Nashville, while Interstate 75 serves Chattanooga and Knoxville and Interstate 55 serves Memphis. Interstate 81 enters the state at Bristol and terminates at its junction with I-40 near Dandridge. I-155 is a branch highway from I-55. The only spur highway of I-75 in Tennessee is I-275, which is in Knoxville. When completed, I-69 will travel through the western part of the state, from South Fulton to Memphis. A branch interstate, I-269 also exists from Millington to Collierville.
A:
Chattanooga
