Problem: Software testing:

Software faults occur through the following processes. A programmer makes an error (mistake), which results in a defect (fault, bug) in the software source code. If this defect is executed, in certain situations the system will produce wrong results, causing a failure. Not all defects will necessarily result in failures. For example, defects in dead code will never result in failures. A defect can turn into a failure when the environment is changed. Examples of these changes in environment include the software being run on a new computer hardware platform, alterations in source data, or interacting with different software. A single defect may result in a wide range of failure symptoms.

What is the first step that leads to a software failure?
---
A: programmer makes an error


Problem: Statehood for Alaska was an important cause of James Wickersham early in his tenure as a congressional delegate. Decades later, the statehood movement gained its first real momentum following a territorial referendum in 1946. The Alaska Statehood Committee and Alaska's Constitutional Convention would soon follow. Statehood supporters also found themselves fighting major battles against political foes, mostly in the U.S. Congress but also within Alaska. Statehood was approved by Congress on July 7, 1958. Alaska was officially proclaimed a state on January 3, 1959.
From which areas did Alaskan supporters face political challenges?
---
Answer: mostly in the U.S. Congress but also within Alaska


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Classical statistical mechanics requires the existence of h (but does not define its value). Eventually, following upon Planck's discovery, it was recognized that physical action cannot take on an arbitrary value. Instead, it must be some multiple of a very small quantity, the "quantum of action", now called the Planck constant. Classical physics cannot explain this fact. In many cases, such as for monochromatic light or for atoms, this quantum of action also implies that only certain energy levels are allowed, and values in between are forbidden.
Regarding atoms, what are values in between certain energy levels considered by the Planck constant?
A: forbidden


Context and question: Politically, Orthodox Jews, given their variety of movements and affiliations, tend not to conform easily to the standard left-right political spectrum, with one of the key differences between the movements stemming from the groups' attitudes to Zionism. Generally speaking, of the three key strands of Orthodox Judaism, Haredi Orthodox and Hasidic Orthodox Jews are at best ambivalent towards the ideology of Zionism and the creation of the State of Israel, and there are many groups and organisations who are outspokenly anti-Zionistic, seeing the ideology of Zionism as diametrically opposed to the teaching of the Torah, and the Zionist administration of the State of Israel, with its emphasis on militarism and nationalism, as destructive of the Judaic way of life.
What ideology do many Orthodox Jews see as in support of the Torah?
Answer: unanswerable


Question: The Late Cretaceous spans from 100 million to 65 million years ago. The Late Cretaceous featured a cooling trend that would continue on in the Cenozoic period. Eventually, tropics were restricted to the equator and areas beyond the tropic lines featured extreme seasonal changes in weather. Dinosaurs still thrived as new species such as Tyrannosaurus, Ankylosaurus, Triceratops and Hadrosaurs dominated the food web. In the oceans, Mosasaurs ruled the seas to fill the role of the Ichthyosaurs, and huge plesiosaurs, such as Elasmosaurus, evolved. Also, the first flowering plants evolved. At the end of the Cretaceous, the Deccan traps and other volcanic eruptions were poisoning the atmosphere. As this was continuing, it is thought that a large meteor smashed into earth, creating the Chicxulub Crater in an event known as the K-T Extinction, the fifth and most recent mass extinction event, in which 75% of life on earth went extinct, including all non-avian dinosaurs. Everything over 10 kilograms went extinct. The age of the dinosaurs was over.
Is there an answer to this question: What climate was restricted to the equatorial areas?

Answer: tropics


In the last years of the nineteenth century, Planck was investigating the problem of black-body radiation first posed by Kirchhoff some forty years earlier. It is well known that hot objects glow, and that hotter objects glow brighter than cooler ones. The electromagnetic field obeys laws of motion similarly to a mass on a spring, and can come to thermal equilibrium with hot atoms. The hot object in equilibrium with light absorbs just as much light as it emits. If the object is black, meaning it absorbs all the light that hits it, then its thermal light emission is maximized.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is known about the light absorption of a hot object in equilibrium with light?
Ah, so..
absorbs just as much light as it emits
