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.

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

To reduce side effects of PANTOPRAZOLE (PROTONIX®️), be sure to swallow the tablets whole with a drink of water (8 oz); do not crush, break, or chew. Take your doses at regular intervals. In addition, avoid frequent use of drinks with caffeine or alcohol, smoke, and illegal drugs.

Some of the more severe side effects of PROTONIX®️ that require for you to contact your prescriber or health care professional are listed at DrugDigest.org. And these are:

fever or sore throat
redness, blistering, peeling or loosening of the skin, including inside the mouth
skin rash, itching
unusual bleeding or bruising
unusual weakness or tiredness
yellowing of the eyes or skin

Less serious side effects are side effects that usually do not require medical attention, but it is recommended that you report to your prescriber or health care professional if they continue or are bothersome. These are:

diarrhea
dizziness
dry skin
headache
nausea/vomiting
stomach pain or gas
tiredness

Both of these medicines, RABEPRAZOLE (ACIPHEX™️) and PANTOPRAZOLE (PROTONIX®️), prevents the production of acid in the stomach. Therefore the side effects are the same.

Hope this answers your question,

There are various procedures to recover data from standard ATA Hard Disks. If you are relatively unexperienced with computers, I would suggest going to a professional in your area to restore the data. If you're willing to take the time try stellarinfo, it's highly recommended. I've left a couple of links for you as well. Also, you may try Norton Ghost, ghost the partition or disk and then go back in through Ghost Explorer and extract the files that way.
