Input: Article: One advantage of the black box technique is that no programming knowledge is required. Whatever biases the programmers may have had, the tester likely has a different set and may emphasize different areas of functionality. On the other hand, black-box testing has been said to be "like a walk in a dark labyrinth without a flashlight." Because they do not examine the source code, there are situations when a tester writes many test cases to check something that could have been tested by only one test case, or leaves some parts of the program untested.

Now answer this question: What can black-box testing sometimes be referred to with the in-ability to see the code?

Output: like a walk in a dark labyrinth without a flashlight.

Input: Article: In addition there are two service bells, cast by Robert Mot, in 1585 and 1598 respectively, a Sanctus bell cast in 1738 by Richard Phelps and Thomas Lester and two unused bellsone cast about 1320, by the successor to R de Wymbish, and a second cast in 1742, by Thomas Lester. The two service bells and the 1320 bell, along with a fourth small silver "dish bell", kept in the refectory, have been noted as being of historical importance by the Church Buildings Council of the Church of England.

Now answer this question: When were the two service bells cast?

Output: 1585 and 1598

Input: Article: Although not yet tested as a therapy in humans, a growing body of evidence indicates that zinc may preferentially kill prostate cancer cells. Because zinc naturally homes to the prostate and because the prostate is accessible with relatively non-invasive procedures, its potential as a chemotherapeutic agent in this type of cancer has shown promise. However, other studies have demonstrated that chronic use of zinc supplements in excess of the recommended dosage may actually increase the chance of developing prostate cancer, also likely due to the natural buildup of this heavy metal in the prostate.

Now answer this question: What kind of cancer cells may zinc prove to kill?

Output:
prostate
