Input: Article: Material transport elevators generally consist of an inclined plane on which a conveyor belt runs. The conveyor often includes partitions to ensure that the material moves forward. These elevators are often used in industrial and agricultural applications. When such mechanisms (or spiral screws or pneumatic transport) are used to elevate grain for storage in large vertical silos, the entire structure is called a grain elevator. Belt elevators are often used in docks for loading loose materials such as coal, iron ore and grain into the holds of bulk carriers

Now answer this question: What are spiral screws used for?

Output: to elevate grain for storage in large vertical silos

Here is a question about this article: From earliest days, Virginia, and Richmond in particular, have welcomed live theatrical performances. From Lewis Hallam's early productions of Shakespeare in Williamsburg, the focus shifted to Richmond's antebellum prominence as a main colonial and early 19th century performance venue for such celebrated American and English actors as William Macready, Edwin Forrest, and the Booth family. In the 20th century, Richmonders' love of theater continued with many amateur troupes and regular touring professional productions. In the 1960s a small renaissance or golden age accompanied the growth of professional dinner theaters and the fostering of theater by the Virginia Museum, reaching a peak in the 1970s with the establishment of a resident Equity company at the Virginia Museum Theater (now the Leslie Cheek) and the birth of Theatre IV, a company that continues to this day.
What is the answer to this question: What family of actors notably performed in 19th century Richmond?
****
So... Booth


The problem: Answer a question about this article:
If the aircraft are VTOL-capable or helicopters, they do not need to decelerate and hence there is no such need. The arrested-recovery system has used an angled deck since the 1950s because, in case the aircraft does not catch the arresting wire, the short deck allows easier take off by reducing the number of objects between the aircraft and the end of the runway. It also has the advantage of separating the recovery operation area from the launch area. Helicopters and aircraft capable of vertical or short take-off and landing (V/STOL) usually recover by coming abreast the carrier on the port side and then using their hover capability to move over the flight deck and land vertically without the need for arresting gear.
What does the angled deck separate the recovery operation area from?
****
The answer: the launch area


Problem: Please answer a question about the following article about Unicode:
In terms of the newline, Unicode introduced U+2028 LINE SEPARATOR and U+2029 PARAGRAPH SEPARATOR. This was an attempt to provide a Unicode solution to encoding paragraphs and lines semantically, potentially replacing all of the various platform solutions. In doing so, Unicode does provide a way around the historical platform dependent solutions. Nonetheless, few if any Unicode solutions have adopted these Unicode line and paragraph separators as the sole canonical line ending characters. However, a common approach to solving this issue is through newline normalization. This is achieved with the Cocoa text system in Mac OS X and also with W3C XML and HTML recommendations. In this approach every possible newline character is converted internally to a common newline (which one does not really matter since it is an internal operation just for rendering). In other words, the text system can correctly treat the character as a newline, regardless of the input's actual encoding.
What is the code for separating lines? 
A: U+2028


Question: Read this and answer the question

Since the early history of the United States, Amerindians, African–Americans, and European Americans have been classified as belonging to different races. Efforts to track mixing between groups led to a proliferation of categories, such as mulatto and octoroon. The criteria for membership in these races diverged in the late 19th century. During Reconstruction, increasing numbers of Americans began to consider anyone with "one drop" of known "Black blood" to be Black, regardless of appearance.3 By the early 20th century, this notion was made statutory in many states.4 Amerindians continue to be defined by a certain percentage of "Indian blood" (called blood quantum). To be White one had to have perceived "pure" White ancestry. The one-drop rule or hypodescent rule refers to the convention of defining a person as racially black if he or she has any known African ancestry. This rule meant that those that were mixed race but with some discernible African ancestry were defined as black. The one-drop rule is specific to not only those with African ancestry but to the United States, making it a particularly African-American experience.

When did the criteria for membership in mixed race groups diverge?
Answer:
in the late 19th century
