5. A. How often X. Read the text carefully, then do the tasks. People visiting Spain for the first time can find it difficult to get used to the eatingcustoms UI the Spanish. It's not so much the food itself, but the timing of the meals that visitors aren't used to. I used to live in Cadiz myself for a few years and I actually quite like the way they do things. Breakfast is a light continental affair- just a roll and some coffee usually- eaten between 8 and 9.30 a.m. The main meal of the day is lunch, which people usually eat sometime between 1.30 p.m. and 3.30 p.m. Quite a few of the shops, museums and galleries close around this time, because the locals like to take time over lunch. They will rest for a short time afterwards, although the traditional afternoon siesta is not as common as it used to be. People eat late in the evening- rarely before 9 p.m. and at the weekend the locals often won't eat before 11 p.m. or even midnight. This is a much lighter meal than lunch- often just a few tapas taken with a drink. A. Decide whether the following sentences are true or false. 1. Mealtimes in Spain can be confusing for visitors. 2. In Spain, breakfast is the largest meal of the day. 3. Spaniards like to have a long lunch. 4. The entire country closes up shop from about 1:30 to 3:30 p.m. 5.
