Read the following article and answer the question. Article: As you are soon on your way to Eastern Europe, here are a few tips on what you should pack. In general, pack lightly, with only the most basic clothes. People dress casually in Eastern Europe, so you don't need to bring along your smartest clothing. Batteries: If your camera, flash, or other appliances run on batteries, bring enough supply along. Certain types of batteries don't exist in Eastern Europe, and those that do often don't last very long. Cash: We have found it good to have supply of small-unit U.S. bills($1and $5) to use in hard-currency stores, to buy international train tickets, etc. The hard-currency stores never seem to have the right _ . Electric Current Adapter : If you bring any appliances, remember that the electricity in Eastern Europe uses 220 volts A.C., not the standard 110 volts of North America. A 110 volts appliance will soon burn out when attached to an unchanged 220-volt plug. Language Tools: One of Europe's biggest challenges is communicating with the local people since their languages are so different from our own. To help overcome difficulties, you might buy phrasebooks before you go -- you won't find them once you are in Eastern Europe. Money Belt: A money belt is especially helpful when you have many documents to carry around ( as you always do in Eastern Europe). The best one we find is made by Eagle Greek Travel Gear, 143 Cedros Ave. (P. O. box 651), Solona Beach, CA 92075 (tel. 619/755 - 9399, or toll free 800/874 - 9925) outside California. Traveler's _ : These are necessary. Bring your traveler's checks in small to medium unit ($10, $20, or $50) to change a little bit at a time, so as not to be left with a lot of local money. To be on the safe side, be sure to copy down the check numbers in two places, just in case something happens to the checks. Question: Which of the following things may be the biggest challenge in Eastern Europe? Answer:
OPTIONS:
- Appliances.
- Money.
- Language.
- Clothes.

Answer: Language.

Question: Read the following article and answer the question. Article: Saving water is an important part of going _ . As water becomes less and polluted more, conservation becomes more and more important. The less water you use, the less wastewater will end up in our rivers and lakes. Wasting water means that more water needs to be treated and cleaned, a process that requires quite a lot of energy. As it is said above, cutting down on water usage is one of the most important things you can do for your local environment and the planet as a whole. That is why more green households are going blue: cutting down their water footprint by conserving and harvesting water. It may seem like a big concept, but going blue starts with small changes that everyone can make. Something as simple as turning off the tap while you brush your teeth can save a lot of water. Wash your fruits and vegetables in a bowl rather than under a tap to save even more. Make sure that the taps are fully turned off every time you step away from the sink or the shower -- all those little drips can add up to a lot of water waste. Another way of reducing your water footprint is reducing your dependence on the main water supply. Rainwater harvesting can meet a lot of your home's water needs. Many of us already practice rainwater harvesting in a small way. Collecting water from your gutters is a great way to keep your garden green without running the sprinkler . Question: According to the passage, all of these can be used to save water except _ . Answer:
OPTIONS:
- washing fruit and vegetables under a tap
- using a bowl to wash your fruit and vegetables
- making sure taps are fully turned off all the time
- turning off the tap every time after brushing your teeth
Answer: washing fruit and vegetables under a tap
