In one sentence, describe what the following article is about: The first is military, take over a settlement to make defending your empire easier, or to weaken an enemy. The second, and most important, is economics. Your main drive in attacking a settlement is to make more money, either by opening up new trade routes or merely adding more people to tax. Only family members (Generals with portraits) can build forts. These forts must be manned by at least one unit at all times, or they will fall into disrepair, and disappear. Forts can be used to prevent war, and they also makes sure you'll be calling the shots once it starts.
Summary: When choosing where to expand, always keep in mind two factors. Use forts, they can be priceless in their ability to keep enemies out of your territory, to seal mountain passes and shut down bridges.

In one sentence, describe what the following article is about: Check for reddish-brown, wingless, flat insects that are about 0.1 cm to 0.7 cm. Examine the folds of mattresses and sheets for the bugs. Also look for exoskeletons that bed bugs might have shed. Search too for tiny white eggs or eggshells, which are about 0.1 cm, or white bed bug larvae which are about the same size. Recall that 0.4 cm is the equivalent of 1/10th of an inch. Look for reddish or rusty stains on your sheets. These might be caused either by crushed bugs or by the bugs' fecal matter. Wipe any dark or red dots you see on your bedding. If they smear or spread, they are likely bed bug excrement. Look for any signs of bed bugs in your bed frame and in the space between your bed frame and the wall. Also look for bed bugs around your headboard. Check for them in the piping, seams, and tags of your sheets, mattress, and box spring. Be sure to look inside pillow cases and on any throw pillows you might have on your bed. In less extreme cases, bed bugs can be present even if they're not at all visible to the naked eye. Take the age of the mattress and cleanliness of the sheets into consideration. If this happens in a hotel room, check to see if the mattress is covered by a plastic sheet. If not, then there's a much higher chance of infestation.
Summary: Look for live bugs in your bed. Examine your sheets. Inspect your bed frame. Assess the state of the bed.

In one sentence, describe what the following article is about: Since plasma TVs use more power and generate more heat than LCD TVs, it is best to turn the screen off before cleaning. Let the screen remain off for 15-20 minutes. This will allow ample time for the unit to cool before you clean the screen. Failure to do this may cause your cleaning solution to evaporate before it has had enough time to remove any dust, dirt, or contaminants on your screen. You could use a microfiber cleaning cloth or a soft, clean cotton rag. Rub it gently in a circular motion across the TV screen to remove all signs of dust. This should be enough to remove most dirt and dust from your TV screen. Avoid rubbing the screen with wood-based products (e.g., paper towels, toilet paper, tissues) because they can scratch the screen. If stubborn dirty spots persist after wiping the screen dry, you can dampen your cleaning cloth. Spray 2-3 squirts of the cleaning solution on the soft cloth. Do not spray the cleaning product directly onto the screen, or it may saturate the surface and damage the screen. Don't use a stronger chemical cleaner (e.g., ammonia or benzene), as these substances will cloud and dim the displayed image. You can find isopropyl-alcohol based screen cleaners at most PC-supply or electronics stores. Try to find a cleaner designed to clean television or computer screens. Once your cloth is dampened, use it to wipe away any hard-to-clean fingerprints or smudges on the surface of your plasma screen. If the moistened cloth is not cleaning sufficiently, you can spray additional small amounts of cleaner on the cloth. However, don't saturate the screen with liquid cleaner or you may damage the plasma. At no time do you want the cloth wet enough that it causes the solution to drip or run down the screen! After wiping the screen clean with a damp cloth, run a dry cloth over it to soak up any residual moisture. This will prevent your plasma screen from being damaged by the liquid. Once the screen is dry, you can plug the set back in and resume watching TV.
Summary:
Turn off the plasma display and let it cool before cleaning it. Wipe the screen with a soft, lint-free cloth to remove fingerprints and smudges. Spray an alcohol-based screen cleaner onto a clean cloth. Swab the screen with the dampened cloth to remove stubborn dust. Dry the screen with a separate clean, dry cloth.
