Problem: Write an article based on this summary: Go to the WhatsApp website on a computer. Click Mac or Windows PC. Click the green DOWNLOAD button. Wait for the setup file to finish downloading, then double-click it. Wait for WhatsApp to finish installing. Double-click the WhatsApp icon if WhatsApp doesn't open. Open WhatsApp on your phone. Open the WhatsApp code scanner. Point your phone's camera at the QR code.

Answer: It's at https://www.whatsapp.com/. You can download WhatsApp's desktop version from this site. This option is toward the bottom of the webpage. It's on the right side of the page. Clicking this button will prompt the WhatsApp setup file to download, though you may first have to select a download location. It will likely be in your computer's default "Downloads" folder (e.g., the desktop). Once it's done, you'll see the WhatsApp icon, which is a white phone on a green background, on your desktop. A white window with a green illustration will appear while WhatsApp is installing. Doing so will launch WhatsApp's login page, which has a black-and-white checkered box (this is a QR code). If you don't have WhatsApp on your phone yet, you'll need to install it on your iPhone or Android before continuing. Depending on your phone, the path to open the QR scanner will be as follows: iPhone - Tap Settings in the bottom-right corner of your screen, then tap WhatsApp Web/Desktop near the top of the screen. Android - Tap , then tap WhatsApp Web at the top of the menu. After a brief moment, WhatsApp will scan the code, which will give your computer permission to log into WhatsApp. You should now be able to use WhatsApp on your computer! If the QR code has expired, click the arrow in the middle of it to refresh the code. If the code won't scan, make sure that all of the QR code is displayed on your phone's screen--you may need to increase the distance between your phone and your computer screen.

Problem: Write an article based on this summary: Find some sterile saline. Boil some water and use it once cooled. Make a salt water solution.

Answer: Sterile saline, such as that found in first aid kits, is the ideal substance for flushing a contaminated wound. The physical act of washing removes the bacteria and debris, while the saline is so similar to the pH of the body tissues that it causes minimal tissue damage. The trick to using saline is to use large volumes and keep washing until the area looks clean. For a very dirty wound with lots of mud or gravel in it, an alternative is to boil water and then let it cool. Use this water to literally wash the area clean. There is a slight risk using water that it will damage the exposed tissue bed, as it does not have the same composition as body fluids and therefore draws fluid out of damaged tissue. However, medical studies have shown that using tap water to irrigate a wound does not have a huge impact on whether the wound eventually gets infected. Salt water has natural disinfectant properties and is a good standby for cleaning a cat's wound. To make a salt water solution boil the kettle, measure out a cup of water,and add half a teaspoon of salt. Then stir to dissolve and leave to cool. This salt water is also around the same composition as tears and body fluids, so it is less damaging to exposed tissue than commercial disinfectant solutions or water alone.

Problem: Write an article based on this summary: Understand the concept of multiplication and division. Learn the properties of multiplication. Practice your multiplication and division tables.

Answer: The idea behind multiplication is to shortcut adding the same things over and over again. You use multiplication when you have groups of the same size. For example, maybe you have three cups of water that you drank ten times. How many cups of water did you drink total? You could solve this problem by counting adding the amount of times you drank the water from each cup together, or you could clump them into groups to multiply. The idea behind division is splitting equal parts into groups. If you have a pizza with eight slices and four friends, how should you split it up so that each person gets an equal amount of the pizza? In division, that problem would be written as eight divided by four. Each person gets two pieces of pizza. For example, order doesn't matter when you multiply. That's one of the properties that you should learn if you want to learn multiplication. You also should learn multiplication problems that change the order of factors, which is called commutativity, problems that change the grouping of factors, which is called associativity. Becoming familiars of the rules to each number will be a huge help when dividing and multiplying. For example, when you multiple numbers by five the answer will always end in a five or a zero. If you multiply a number by two, it will always end in an even number. Similar rules apply for division. Learn these rules and practice your tables.

Problem: Write an article based on this summary: Purchase a large aquarium. Install a large canister filter. Keep a heater in the aquarium. Add the substrate. Provide the fish with hiding places.

Answer:
Parrot cichlids can grow as large as 10 inches (25cm) long. For this reason, you'll need to buy at least a 42-gallon (159 L) tank if you want to keep only one fish. Aim for 10 additional gallons (38 L) for each fish if you're planning on giving your fish some companions. Parrot cichlids like to have several hiding places along the bottom of the aquarium, so a taller tank wouldn't help. Parrot cichlids are large fish with healthy appetites. Their tendency to dig in the substrate can stir up dirt and algae. This is why they require a larger filter. A heavy-duty wet/dry filter will help to remove these waste products and keep the water clean. Purchase a filter that can be mounted to the back of the tank. Avoid anything that goes under the substrate, as digging fish can easily disturb its functioning. Many breeds of parrot cichlids originate in warm South American climates. Keep the aquarium temperature about 76 to 84F (24 to 29C). Even blood parrot cichlids, bred in captivity by humans, thrive in warmer waters. Temperatures below 80F (27C) might cause cichlids to become less social. Parrot cichlids like to dig, so make sure the substrate is soft. Opt for fine dark sand, which they can comfortably burrow under. Avoid putting plants in the aquarium, since the cichlid's tendency to dig could knock them over. Parrot cichlids can be territorial, especially if you plan on adding smaller tankmates. Keep broken flowerpots, small rocks, driftwood, or stacked rocks to form caves that provide the fish with hiding spots.
