INPUT ARTICLE: Article: Use a ruler or a straight edge to do this. It can be at the top, near the bottom, or anywhere in between. " Be sure the two circles overlap like a Venn diagram. This line marks the diameter of the circle4. Measure it using a ruler, or for greater accuracy, a pair of digital calipers. You're done!

SUMMARY: Draw a horizontal line inside the circle from one edge to the other. Label the points where the line crosses the circle points "A" and "B. Draw two overlapping circles, one using A as the center and the other using B as the center. Draw a vertical line through the two points at which the outer circles intersect. Measure the diameter.

INPUT ARTICLE: Article: The top line should be the greeting you've chosen, followed by the person's name. Use a title for the person when possible, such as Mr., Mrs., or Dr., followed by their first and last name. Generally, you'll use a comma after the greeting. In formal letters, you can use a colon, but that is usually too formal for an email, even a formal one. A comma will suffice in most instances, though you might use a colon if you are writing a cover letter in an email. The greeting goes on its own line at the top, so once you've written it, hit the return key to move to the next line. If you're using line breaks instead of indentions to make paragraphs, you'll need to leave a blank line between the greeting and the first paragraph. If you are writing someone for the first time, you should provide an introduction, even if you know the person in real life. Giving the person a clue to who you are encourages them to keep reading. For example, you could write, "My name is Jessica Hills, and I am the marketing director for XYZ Company." You could also include how you know the person: "My name is Robert Smith, and I'm in your marketing class (Marketing 101 that meets Tuesdays and Thursdays at noon)." If you already know the person and have written them before, you can use the first sentence as a greeting. For instance, you could say, "Thank you for getting back to me so quickly," or "I hope you are doing well." Most formal emails need to get to the point quickly. That means that your first or second sentence should introduce the reason why you're writing to the recipient. Remember to be as concise as possible when describing your purpose. For example, you could write, "I'm writing to ask for your assistance with a marketing problem," or "I'm writing you because I'm having trouble in class, and I was hoping you'd have suggestions for extra material I could read to help."

SUMMARY: Place the greeting on the first line. Use a comma. Move to the next line. Introduce yourself in the opening sentence, if necessary. Get to the point.

INPUT ARTICLE: Article: Unlike appetizers, which offer a variety to please most people in a big party, your main course will be more specific and possibly more polarizing, if a guest doesn't like the food on offer. Choose a simpler, universally-appealing meal if there will be lots of kids in attendance. You can expect a small group of adults to be more flexible and willing to try new dishes. If there's just one or two kids in attendance, consider cooking them a separate, simpler dish, such as a grilled cheese or hot dog. This will give you more freedom to choose a main course just for the adults. for an easier, less formal dish. Chicken is also pretty universally popular and less expensive. You can dress it up with side dishes like roasted potatoes and vegetables. Plan for each guest to eat about 1.5 pieces of chicken. Spinach, asparagus or portobello mushroom is a good choice for a chicken main dish. for a filling, more versatile meal. You can take beef in many different directions: steak or even tri-tip feels more formal, while ribs will make things fun and messy. Consider the atmosphere you want at your dinner party to choose what kind of beef to serve. Each guest's portion size will depend on the amount of bones in the meat. For a boneless cut of meat, buy 4-5oz (115-140 g) per guest. For a cut with bones, such as steak or pork chop, estimate 5-8 oz (115-226 g) per person. And for meat with lots of bones, like ribs, buy 12-16 oz (340-454 g) per person. Mashed potatoes are a traditional favorite side for steak. For a healthier option, try roasted broccoli or brussel sprouts. for a lighter meal at a smaller party. Fish can easily be overcooked, so reserve fish main courses for smaller groups so that you can pay extra attention to your cooking. It's a great option for a party with lots of pescatarians, but make sure to serve with side dishes to make a more filling meal. Buy locally-caught fish for a cheaper, fresher option. You can get creative with fish side dishes, depending on the fish. Potatoes, salad, pasta or even bean salsa can pair very well many different kinds of fish. If the majority of your guests are vegetarians, consider a meat-less pasta with lots of veggies or mushrooms, or even a homemade pizza or frittata. You'll have the advantage of saving money and avoiding the stress of over- or undercooking meat. Research filling vegetarian dishes on the Internet or in vegetarian cookbooks.

SUMMARY: Choose a main course based on your guests' preferences. Serve chicken Serve beef Serve fish Serve hearty pastas or frittatas for a vegetarian party.

INPUT ARTICLE: Article: Look for a clean jar or empty shoe box to house your woodlice. To keep just a few woodlice, use a small jar. For lots of woodlice, consider purchasing a container, such as a plastic terrarium or glass aquarium from your local pet store. Keep in mind that if you pick a shoe box or small cardboard box, you won't be able to keep the woodlice for more than a day. This is because the moist material and environment will make the container break down quickly. Spread the soil in the container so the bottom is completely covered. Press down a little so the soil is firm enough to support the woodlice and their digging. Add as many woodlice to the container as you like. If you're digging into the soil with a sharp shovel, use caution so you don't accidentally injure woodlice that may be in the ground. Scatter about 1 inch (2.5cm) of leaves across the soil in the container. It's fine to place these over the woodlice since they prefer to be under leaves and soil. You can also add small sticks or twigs and scraps of bark. Your woodlice will eat the leaves and climb around the sticks. Leave rocks out of the container since they can tumble and crush the woodlice, especially if the container is moved. If the container has a lid, close it and ensure that air vents are open. To make your own air vents in a shoe box, put the lid on the box and carefully poke holes in the top. If you're using a jar, cover the jar with waxed paper, plastic wrap, or foil. Then use a sharp skewer to poke holes across the top. Use caution or ask for help when poking holes in the lid. Ensure that the holes aren't big enough that the woodlice can escape. Put it out of direct sunlight so the woodlice don't overheat. Since woodlice prefer a cool environment, you don't need to use any special heat lamps, just keep the container inside your house. If you have other pets or small children, put the woodlice container somewhere out of their reach.

SUMMARY:
Choose a sturdy container to hold the woodlice. Put 2 inches (5.1cm) of soil in the container and add the woodlice. Add leaves, sticks, and bark to give the woodlice something to explore. Cover the container and poke air holes across the top. Place the woodlice container in a secure spot in your house.
