Article: Pour 4 parts of water into a saucepan on your stove and set the burner on high. As the water warms, add in 1 part of white sugar. Bring the water to a low boil, and let it boil for 2–3 minutes so the water and sugar blend. Then, let the water cool for 30 minutes, and pour it into your feeder.  The size of the carafe varies from one hummingbird feeder to another. Only make enough nectar to fill the carafe of your feeder(s). If you make extra, you can store it in the refrigerator. The nectar will only keep for about 1 week, though. Never use honey or artificial sweeteners in your nectar, and never give hummingbirds commercial foods that contain red dye. Due to the high sugar content of the nectar, the feeders get dirty quickly. To clean them, mix white vinegar and warm water at a ratio of 1:4. Dump out the old, dirty water, and pour in about 1⁄2 litre (0.13 US gal) of the vinegar solution. Place the lid back on the feeder and shake it vigorously to clean out the feeder. If the inside of the feeder is especially dirty, drop 12–20 grains of rice in along with the vinegar mixture. The rice will scrape stains or moldy patches out from the carafe. Once it’s clean, rinse the feeder out 2–3 times with warm water to remove all traces of the vinegar mixture. If any vinegar is left inside, birds will stop drinking from the feeder. Then, refill the feeder with another batch of sugar water for the birds to eat. Hang the feeder again, and watch as more of the beautiful birds come by to drink! Ants are a problem for all hummingbird feeders, but get especially bad with suction-cup feeders, since ants have easy access to them. Prevent ants from accessing your feeders by filling up the feeders’ ant moat with water. The ant moat is a 3–4 in (7.6–10.2 cm) wide trough that goes around the feeder. When ants attempt to get to the sweet nectar, they’ll fall and drown in the moat. At least once a week, scoop the ant bodies out of the ant moat and dispose of them.  Most saucer and J-hook feeders have ant moats. Suction-cup feeders often don’t, since the moat would be unable to wrap all the way around the feeder. If you’re concerned about ants and wasps getting into the nectar and bothering the hummingbirds, purchase a bee guard that can be attached to the feeder. Most hardware stores sell bee guards.  Never fill the moat with oil. Small birds will drink from the moat from time to time, and the oil could harm them. If you don’t take preventative steps, you’ll soon find that your feeder is full of drowned ants and that the birds are no longer drinking from it.
Question: What is a summary of what this article is about?
Fill the hummingbird feeder with nectar made from sugar and water. Clean the feeder with vinegar and warm water once a week. Rinse the carafe with warm water and refill the feeder. Keep ants away by filling the feeder’s ant moat with water.

Problem: Article: Open up your rabbit’s hutch or enclosure to look around and smell it. Check for any areas that are particularly damp or any areas with waste in them that haven’t been cleaned recently. If the odor is coming from the rabbit’s hutch, you might not be cleaning it often enough. Clean out any soiled or dirtied hay in the rabbit’s hutch each morning and replace it with new hay for your rabbit to sit in.  If you can’t clean the hutch each day, you should be doing it every other day at the absolute minimum. If you don’t want to clean out the entire hutch, you could try litter train your rabbit so you only have to clean a small area or a litter tray. Your rabbit’s enclosure should smell like clean hay, which many find quite pleasant. If you smell anything stronger than this, it’s likely that you’ve found the source of the stink. Even if you’re cleaning out soiled hay each morning, some bad smelling substances can seep into the hutch itself. Clean the hutch thoroughly once each week by removing everything, scrubbing the hutch down with warm soapy water, misting lightly with white vinegar to disinfect it, and rinsing thoroughly with water. You should also clean your rabbit’s food bowl and its water bottle or bowl when you clean out the hutch weekly. If the hutch is still wet or damp when you put hay back into it, the hay may begin to rot and produce a bad smell. Let your rabbit run around freely or keep it in a small, temporary cage while the hutch dries completely.  You should be able to tell by touch if the hutch is still damp. Feel the inside for any dampness, leaving it to dry for longer if it is still wet. As long as you keep a few doors closed to prevent the rabbit from traveling too far, it should be perfectly content hopping around your home while its hutch dries.
Summary: Inspect the rabbit's hutch to determine if it's the source of the smell. Replace soiled hay each morning. Clean the whole hutch thoroughly once a week. Leave the hutch to dry in the sun for 3 to 4 hours.

Stretch your hands in front of you in a streamline position. Keep your feet and legs straight and together, and keep your core tense.  You should start off low enough in the water that you’ll be able to keep your whole body underwater while you execute the stroke. You might need to start off at a slight downward angle in order to achieve this, and it will probably take some practice. Be sure to breathe in fully before starting, since you’ll be under water for a while. You can do the dolphin stroke on your back, your front, or even your side, but when you’re learning it, it’s probably easier to start prone, with your face toward the bottom of the pool. Tilt your pelvis forward slightly to drive this motion. This part of the stroke is the backward kick, and it is meant to get your body into position.  Focus on achieving a full extension with your legs. Tilt your pelvis backward to drive this part of the stroke. This is the forward kick, which provides the stroke’s propulsion. Your legs should extend in front of your body line during this part of the kick. Feet, like a dolphin’s fins, generate much of the thrust in this kick. Fully extending your ankles can maximize this effect. This is an unusual position in daily life, but strong, flexible ankles will improve all of your swimming kicks, not only the dolphin.  In essence, you are pushing water, not only up and down, but also backward with this kick. Flexible, extended ankles are crucial to doing this effectively.  Strengthen and stretch your ankles by tracing the alphabet with your feet. Lie on your back in a comfortable position and write each letter, lowercase and uppercase, in the air with each foot. Don’t use the motion of your hips to stay underwater. Instead, control your depth using your arms. By keeping your arms in streamline position and pointing them slightly toward the bottom of the pool, you will resist the tendency of your body to float to the surface. The kick’s power is based in part on the insight that kicking underwater avoids the resistance created by turbulence and air at the surface.
