Q: You can rent a car from the airport and throughout rental locations in and around the city. You will need a credit card in order to rent a car. Enter I-40 and take it as far as Williams, Arizona. This is approximately 420 driving miles. Drive approximately 60 miles to arrive at the South Rim of the Grand Canyon. The total trip time on this route is about 8 hours.  This is the most direct route to the Grand Canyon from Los Angeles, because other modes of transportation require you to go through Flagstaff, Arizona. You can also follow I-40 to Flagstaff, Arizona, and then take Route 180 north to the Grand Canyon. This will take approximately 1 hour longer to drive.
A: Rent a car in Los Angeles, if you don't have one. Find Interstate 40 (I-40) from your starting location. Take Arizona Highway 64 (AZ-64) north at Williams, Arizona.

Article: Make sure to leave the sidewalks clear for the firefighters to do their work. If there are too many people clumped on the sidewalks, firefighters cannot get through. Be sure to listen for people in authority giving directions. Teachers or your bosses will likely be looking to take a head count, so they will want to get everyone in the same area, which is why it's important to stay quiet. If there really is a fire, the building could eventually collapse. You should move a safe distance away from the building. Generally, across the street is fine. Don't assume that because the fire alarm has stopped, you can re-enter the building. Wait until the firefighters or someone else in charge tells you it's fine to go back inside. Once you hear that, you can resume normal activities.
Question: What is a summary of what this article is about?
Clear the sidewalks. Move to a safe distance. Wait for the all-clear.

Problem: Article: Watch Michael Dickinson's TED talk on how flies fly to gain awesome insight. .. well... uh... hinges on the hinges where the wings attach to the body. If these are immobilized, the fly becomes a "walk." Chemists all around the world have worked in labs for years— formulating, testing and refining stiffening products for the hair. Guess what? The hairspray does not know what it is stiffening. It indiscriminately stiffens everything it hits, fly wings and fly wing-hinges included. (Don't worry.— You will not get put on any lists for this kind of stalking.) Simply observe the fly and get in a good position to intercept the flight path of the proudly parading pesky pest. Zing. You got a tumbler!... and a walker. Invert the glass and place it over the fly.   Bye, bye dead fly. Note: this burial at "sea" can be just as ceremonious as you want, but there is no real need to go out of your way. It is only a fly... walk... goner.
Summary: Take the time to study the capabilities of your nemesis (the fly). Realize that most of the maneuvering done by a fly hinges on the. Know that hairspray is the ultimate stiffener. Stalk your victim. Douse her (or him) with a good shot of hair spray. Trap the fly with a clear drinking glass. Slide an index card under the glass and the fly. Take the fly carrier (glass & index card assembly) into the bathroom. Dump the fly into the toilet and flush.

INPUT ARTICLE: Article: First, pre-weigh a container. Next, take the weight of the container again, but this time with a specified volume of your liquid inside. Subtract the weight of the liquid-filled container from the weight of the empty container. The difference is the weight of your liquid.  For example, if your container weighed 1.50 pounds with liquid in it and 1.00 pound empty, your equation would look like this: "1.50 lb - 1.00 lb = 0.50 lb." Your liquid weighs 0.50 pounds. Make sure the temperature of your liquid is noted when this weight is taken. You must compare it to water of the same temperature. Fill the same container to the same volume. Then, weigh the container and find the weight of that volume of water. You should not need to pre-weigh the container again, since you already know the weight of the empty container.  Use the same formula to find the weight of the water. If the liquid-filled container weighted 1.75 pounds, the equation would look like this: "1.75 lb - 1.00 lb = 0.75 lb." In this example, the water weighs 0.75 pounds. Make sure that the water is at the exact same temperature as the liquid in question. Otherwise, results may not be accurate. Since you are dividing one weight by another, the units will cancel out. This makes specific gravity a unitless measurement. Use the ratio "Wl / Wwater” where Wl is the weight of your liquid and Wwater is the weight of water. For example, if you weighed 100 mL of acetone at 25 degrees Celsius, it would weigh 0.17314 pounds. Weighing the same volume of water at the same temperature would give you 0.22 pounds. To find the specific gravity of this acetone, you would solve 0.17314lbs/0.22lbs=0.787{\displaystyle 0.17314lbs/0.22lbs=0.787}. This is the specific gravity of acetone.

SUMMARY: Obtain a weight for the liquid in question. Obtain the weight of an identical volume of water. Calculate the ratio of the liquid’s weight to the weight of water.

Q: This can be a spreadsheet file, database file, or even a text document with the proper formatting. Spreadsheet files are most commonly used; this guide assumes you are using a spreadsheet.  Your data file should have all the information that will have to change from copy to copy. For example, if you're writing a form letter, your data file will hold the names and possibly the addresses of everyone you intend to send the letter to. Put one item of information in each cell along a line, so that each type of information (first name, last name, honorific, and so on) is in its own column.  Make sensible column names. Mail merge reads data in columns. It will assume that the first entry in each column of information is the general name for that type of information, so use names that make sense for you. For example, start a column of first names by typing “firstname,” then put all the first names below it. When you are asked which field to insert into your letter, you will see “firstname” as an option and remember what is contained in that column.  Microsoft Office users who also use Outlook for their e-mail can use their Outlook address book as a data file instead, if desired. Save it somewhere you can find it easily, and name it something you will easily remember. This is the document you will be inserting information into. For example, if you're writing a form letter, the primary document is the letter. Any item that mail merge will fill in for you (such as names) should be left blank for now.
A:
Build a data file. Save the data file. Write out your primary document.
