Read the following passage and choose the correct answer to each of the questions that follow by writing A, B, C, or D in Your answers box

Canning is a method of preserving food over extended periods of time. The process involves sealing food in containers and heating it in order to kill bacteria that could eventually cause spoilage. While most canned food is produced by commercial companies, some is done at home. Homegrown fruits and vegetables such as apples and tomatoes are the most popular foods to can. Even certain kinds of meats are suitable for canning. However, it is not advisable to heat products such as avocados because of the changes in taste and texture that occur. Other foods, including cucumbers and peppers, can be canned only if they are first pickled and then cooked at very low temperatures. Properly canned food can be saved for as long as three years. If not properly sealed, the food can be spoiled by the growth of organisms. In severe case, bacteria can cause a fatal form of poisoning called "botulism". For this reason, it is very important to check the seal of the jar or bottle regularly to make sure it has remained undisturbed.

In Western countries, electricity, gas, and water are not luxuries but necessities. Companies now realize that consumers want products that will not only work effectively, but also save money.

For most North American households, lighting accounts for 10 percent to 15 percent of the electricity bill. However, this amount can be reduced by replacing an ordinary 100-watt light bulb with an energy-saving bulb. These bulbs use a quarter of the electricity of standard bulbs and last eieht times longer. Therefore consumers can save about US$7 to US$21 per bulb.

In Europe, there is a labeling scheme for refrigerators, freezers, washing machines and tumble dryers. The label tells the consumers how much energy efficiency each model has, compared with other appliances in the same category.

Ultimately, these innovations will save money as well as conserve the Earth's resources.
