Q: The lens of your pug's eye might seem cloudy and bluish-gray. Eventually, the cataract covering the lens can cause your dog to lose his vision. The cataract might look crackly or like a chip of ice. Cataracts form either due to genetic predisposition, trauma, diabetes or other diseases. If a cataract is covering your dog's eye, she may have trouble seeing. As a result, she may be clumsier and less sure of her surroundings. You may also notice your dog:  Bumping into things. Not recognizing people. Misjudging distances. Make an appointment with the veterinarian as soon as you notice the milky eyes. The vet can usually diagnose cataracts simply by looking at your dog's eyes and a veterinary surgeon can confirm the diagnosis. If your dog his older, his lens may simply be aging but it shouldn't affect his vision too much. The vet will check for this. Cataracts in the early stages may make her vision blurry, but a mature cataract will cause blindness, so you might want to surgically remove it. During surgery a specialist surgeon will remove the lens and replace it with an artificial one. Or, the cataract can be broken down by a laser in a procedure known as phacoemulsification. If you want your pug to get surgery, it's important to do it before your dog's vision worsens.
A: Watch for milky eyes. Pay attention to your dog's behavior. Get your pug examined. Get surgery for cataracts.

Article: You might use half an envelope or a paper box. The size of the container will necessarily depend on the size of the bridge you have built. Use a string or bent paperclip to attach the container to the center of the bridge. A thin bridge may break immediately after you attach the container, but a thicker, stronger spaghetti bridge will hold. You can use multiple hanging points to distribute the weight evenly across the bridge. Alternatively, you can place the weight directly on the roadbed of the bridge. However, this will increase the chances of you accidentally collapsing the bridge when placing weights on it, so be very careful. Again, the size and density of the weighted objects will depend on the size of the bridge you built. For smaller bridges, coins will work as weighted objects. For larger bridges, consider using something like bags of sand or, if your bridge is quite large, actual weights from a weight set. Make sure you know the actual weight of the objects you use so that you can accurately determine how much weight you’ve added to the bridge before it collapses. Begin to add weights to the container a little at a time. Take care not to jar the bridge or cause the container to swing. This can be a very nerve-wracking process. Eventually, you will have added too much weight for your bridge to hold and it will collapse. After enjoying the bridge’s destruction, determine how much weight the bridge held by calculating the sum of the weights you added to the bridge. You will now want to go through this process again making minor alterations to the materials or adjustments to how you constructed the bridge. The goal here is to see if you can build a stronger bridge capable of holding more weight. Like any good science experiment, a little trial and error will be necessary.
Question: What is a summary of what this article is about?
Hang a lightweight container under the center of the bridge. Acquire weighted objects. Add weight. Watch the bridge collapse. Go back to the drawing board.

Problem: Article: Videos you've captured with your iPhone can be found in this app. Trimming your video will allow you to cut out and remove any unnecessary or redundant portions of the video.

If you want to cut the beginning off of the video, you can tap and drag the arrow at the bottom-left corner of the video to a new starting point. Tap Play icon (the white triangle at the bottom) to see a preview of the video's new starting point. If you're unsatisfied, keep dragging that arrow until you're at the right spot. It's at the bottom-right corner of the video.  Tap the Play icon again to see a preview, and make any necessary changes. The part of the video that will remain after you trim is the part inside the yellow box. It's at the bottom-right corner of the screen. Some options will expand at the bottom. The first option will save over the original video file with your new changes. If you don't want to modify the original video file, select Save as New Clip to create a new, separate file for the trimmed video.
Summary: Open the Photos  app on your iPhone. Tap the video you want to edit or trim. Tap Edit. Drag the left-arrow to place you'd like the video to begin. Drag the right-arrow to the desired stopping point. Tap Done to trim the clip. Tap Trim Original or Save as New Clip.

Q: Drinking an espresso is an experience in and of itself. And to help you make the most of this pleasure, here are a few tips:  Look at the espresso. Ideally, a shot will be rich brown in color with some speckling or flecking of copper or dark gold. The top layer is called crema, a rapidly-evaporating compound of coffee oils and solids. The thicker and richer the crema, the better the shot is likely to be. The heart of the shot is a dark, almost black, syrup-like layer beneath the crema. Drink fast! Espresso begins to deteriorate within fifteen seconds of extraction. Take the tiny cup, or demitasse, and slurp to throw the espresso against the back of your palate. Expect a shock. Espresso is one of the most astonishing taste sensations in the world, but if done right, is never bitter. Keep slurping, tasting for elements such as spice, fruit, wood, or smoke. Every shot is slightly different. Discuss your findings with your barista to see what he or she “gets” from the shot. Making an espresso is an art form for many baristas and you can learn a lot by engaging them in a discussion.
A:
Enjoy your espresso.
