Problem: Article: It is important that you carefully follow all of the instructions provided in order to receive accurate results. For example, during the test you will likely be asked to cover one of your eyes with your hand and then answer a variety of questions. You will then be asked to cover your other eye and answer another set of questions. This is done in order to test the vision in each of your eyes. You may be asked to leave your glasses on if you already wear glasses to help with your vision. When taking a visual acuity test, an "E" will appear on your screen and you will be asked to select the arrow that the open side of the "E" is facing. The "E" will rotate and change sizes as you complete the test. Depending on the website you are using you may be asked to cover one eye and take the test and then repeat the questions with your other eye covered. An online vision test that looks at your ability to see contrast can also help determine if you need corrective lenses. To complete this test, a "C" will appear on your screen and you will be asked to select the arrow that the open side of the "C" is facing. As you complete the test the "C" will rotate and the darkness of the letter will change. For example, in some instances the letter will be very dark and easy to read and at other points it will be so light that it will become difficult to see against the white background. A colour vision test will check to see if you can distinguish different colour contrasts, most notably red, green, and blue. These tests vary slightly, but in most cases a circle will appear that is filled with different coloured circles. You will then be asked to read the number that is hidden inside the circle. If you are not colour blind you should be able to see the numbers easily based on the contrasting colours. An online astigmatism test will ask you to cover one eye and look at a series of lines. You will be asked if some of the lines appear darker than others. Then you will then be asked to cover your other eye and determine if some of the lines are darker than others. You should only see darker colours with one of your eyes, not both. If this happens you may have astigmatism and should talk with your eye doctor. At the end of each test you will be given your results. You may receive excellent results for each test. This indicates that your vision is good and you likely do not need glasses. For some tests, you may receive a poor result. When this happens the site will recommend that you see an eye care professional in order to receive a full eye exam. Some sites will only provide you with results after you have provided your email address and name.
Summary: Follow the instructions. Test your visual acuity. Take a contrast vision test. Try a colour vision test. Take a test that measures astigmatism. Read your results.

INPUT ARTICLE: Article: Blue-ringed octopuses are found across most Australian coastlines and they spend most of their time hiding. Look for small, 1220cm (4.77.9in) brown octopuses around rocks and shells, and leave the water immediately if you spot one. When these creatures feel threatened, they develop bright blue lines and rings, making them much easier to spot. Blue-ringed octopuses aren't aggressive and are actually quite shy, but they will bite if touched. Most blue-ringed octopus bites are accidental, as it's easy to touch or stand on one without noticing. Box jellyfish have a bell (body) that looks like a box with 4 corners. Each corner has up to 15, 3m (9.8ft) long tentacles. Irukandji are only the size of a fingernail, yet have tentacles that can each extend up to 1m (3.3ft) long. Beaches in Queensland, Northern Territory, and Western Australia are home to box jellyfish and Irukandji. Rely on signals like washed up jellyfish, clouds of small prawns, and calm weather with a northerly breeze, as it can be difficult to spot these types of jellyfish in the water. Irukandji syndrome develops within minutes of a sting and the symptoms include back pain, nausea, and difficulty breathing. Seek emergency medical treatment and pour vinegar over the site if possible. Bluebottle jellyfish are 215cm (0.795.91in) long and look like thin, blue bubbles. They relatively easy to spot in clear water and the tide is often littered with bluebottle bodies if these small jellyfish are close by in the sea. Don't touch washed up jellyfish, as they can still sting. Although cone shells look like innocent, pretty shells, they are actually predatory sea snails which have teeth similar to a harpoon. These sea snails are approximately 12cm (4.7in) long and they have a bright shell pattern in brown and cream. When a cone shell is disturbed, the tooth injects a potentially deadly venom into the victim. Cone shells are found under sand, stones, and weeds throughout Western Australia, Northern Territory, and Queensland.

SUMMARY: Expect blue-ringed octopuses in shallow reefs and coral rock pools. Watch out for box jellyfish and Irukandji at tropical beaches. Check the beach for washed up jellyfish to spot bluebottles. Avoid touching any shells to prevent a cone shell attack.

In one sentence, describe what the following article is about: These two tabs, located next to the power plug, will probably need to be popped at the same time (they can be done one at a time but this is more difficult). This is when you will want to take advantage of the second small screwdriver. Using both of these or the case opening tool, pop the tabs and start to pry the shell open. At the other end of that side, you will see five more of these tabs. Pop them one at a time, keeping constant pressure as you open the shell, or use the case tool to open them all at once. Flip the 360 around to look at the front end, find the clip at the end near the DVD drive. This can be easily opened with your fingernail or a flathead screwdriver and a good deal of prying. There should be four tabs on this side, which you can take one at a time. With the shell removed, you should be able to see the inner casing now. Open this by unscrewing the cover panel. Flip the Xbox onto the opposite side and pull off the remaining shell to reveal the inner components.
Summary:
Open the two hole tab section. Open the five hole tab section. Ease open the shell. Unscrew the inner casing.
