Input: Article: One of the ways to prevent or slow down the transmission of infectious diseases is to recognize the different characteristics of various diseases. Some critical disease characteristics that should be evaluated include virulence, distance traveled by victims, and level of contagiousness. The human strains of Ebola virus, for example, incapacitate their victims extremely quickly and kill them soon after. As a result, the victims of this disease do not have the opportunity to travel very far from the initial infection zone. Also, this virus must spread through skin lesions or permeable membranes such as the eye. Thus, the initial stage of Ebola is not very contagious since its victims experience only internal hemorrhaging. As a result of the above features, the spread of Ebola is very rapid and usually stays within a relatively confined geographical area. In contrast, the Human Immunodeficiency Virus (HIV) kills its victims very slowly by attacking their immune system. As a result, many of its victims transmit the virus to other individuals before even realizing that they are carrying the disease. Also, the relatively low virulence allows its victims to travel long distances, increasing the likelihood of an epidemic.

Now answer this question: What are some critical disease characteristics that should be evaluated?

Output: virulence, distance traveled by victims, and level of contagiousness


Article: While Brazil was fighting the US through the WTO's Dispute Settlement Mechanism against a heavily subsidized cotton industry, a group of four least-developed African countries – Benin, Burkina Faso, Chad, and Mali – also known as "Cotton-4" have been the leading protagonist for the reduction of US cotton subsidies through negotiations. The four introduced a "Sectoral Initiative in Favour of Cotton", presented by Burkina Faso's President Blaise Compaoré during the Trade Negotiations Committee on 10 June 2003.

Question: What has the Cotton-4 been in regards to the US cotton subsidies?
Ans: leading protagonist


Here is a question about this article: In ring-porous woods of good growth it is usually the latewood in which the thick-walled, strength-giving fibers are most abundant. As the breadth of ring diminishes, this latewood is reduced so that very slow growth produces comparatively light, porous wood composed of thin-walled vessels and wood parenchyma. In good oak these large vessels of the earlywood occupy from 6 to 10 percent of the volume of the log, while in inferior material they may make up 25% or more. The latewood of good oak is dark colored and firm, and consists mostly of thick-walled fibers which form one-half or more of the wood. In inferior oak, this latewood is much reduced both in quantity and quality. Such variation is very largely the result of rate of growth.
What is the answer to this question: When there is less latewood, what is diminishing?
****
So... breadth of ring


The problem: Answer a question about this article:
Although professional wrestling is worked, there is a high chance of injury, and even death. Strikes are often stiff, especially in Japan and in independent wrestling promotions such as Combat Zone Wrestling (CZW) and Ring of Honor (ROH). The ring is often made out of 2 by 8 timber planks. Many of the injuries that occur in pro wrestling are shoulders, knee, back, neck, and rib injuries. Chronic traumatic encephalopathy and traumatic brain injuries have also been linked to pro wrestling, including in the double-murder suicide case involving Chris Benoit. Professional wrestler Davey Richards said in 2015, "We train to take damage, we know we are going to take damage and we accept that".
What are common injuries in wrestling?
****
The answer: shoulders, knee, back, neck, and rib injuries


Problem: Please answer a question about the following article about Department store:
After World War II Hudson's realized that the limited parking space at its downtown skyscraper would increasingly be a problem for its customers. The solution in 1954 was to open the Northland Center in nearby Southfield, just beyond the city limits. It was the largest suburban shopping center in the world, and quickly became the main shopping destination for northern and western Detroit, and for much of the suburbs. By 1961 the downtown skyscraper accounted for only half of Hudson's sales; it closed in 1986. The Northland Center Hudson's, rebranded Macy's in 2006 following acquisition by Federated Department Stores, was closed along with the remaining stores in the center in March 2015 due to the mall's high storefront vacancy, decaying infrastructure, and financial mismanagement.
What was the Northfield Center renamed after it's purchase by another company?
A: Macy's


Question: Read this and answer the question

On runways, green lights indicate the beginning of the runway for landing, while red lights indicate the end of the runway. Runway edge lighting consists of white lights spaced out on both sides of the runway, indicating the edge. Some airports have more complicated lighting on the runways including lights that run down the centerline of the runway and lights that help indicate the approach (an approach lighting system, or ALS). Low-traffic airports may use pilot controlled lighting to save electricity and staffing costs.

On runways, what indicate the end of the runway?
Answer:
red lights
