instruction:
You are given a passage. You need to construct a question about the information present in the passage. Construct a question in such a way that (i) it is unambiguous, (ii) its answer is the whole paragraph. Avoid creating questions that can be answered correctly without actually understanding the paragraph.
question:
There are two kinds of trading that are referred to as "insider trading" or "inside dealing":

Usually illegal: Trading of a security of a company (e.g., stocks, bonds or stock options) based on material non-public information. The trader may be a corporate "insider" or someone unlawfully obtaining the non-public information (which may constitute a separate offence of spying on trade secrets).

Usually legal: Trading not based on material non-public information by "insiders" of a corporation. (legal)
answer:
What is insider trading?

question:
Materials that form an inverse energy distribution? Not quite.

There are three basic components for getting a laser to work. First, one needs an excitation source (pumping source) such as a flashlamp, an electrical spark, etc. Second, one needs a material (the gain medium) which can exhibit what's known as population inversion - the capacity for a material to raise the electron energy level from the lower to the upper energy states. Nearly all materials will exhibit this behavior with some more efficiently than others. Finally, one needs to direct the stimulated energy by using a resonator.

There are many combinations of pump sources, lasing materials and optical configurations depending on the intended use. There are solid state (ruby, Nd:YAG), gas (nitrogen, helium-neon) and semiconductor (gallium-arsenide) lasers that come in a variety of wavelengths (colors) to choose from, again, depending on what you want to do with it.

Just a little bit of background: My degree is in Physics, and I've been working in the lasers and electro-optics field for the past 10+ years. You can see what my graduate lab at SDSU looked like at: http://www.equationlab.com/mtp/quantumblog/about.html
answer:
what are the materials that can be used to produce laser beam?

question:
Where the computers are. LOL. I work for the IT department in the hospital. There are always computers at the hospital. So try there. Hospitals will always be here. And they will always be up to date with the best software.
answer:
Where are the best IT/Computer jobs located?
