I'm taking a test and have to guess the right answer to the question after the article. Article: Many people believe that the common garden slug[ is nothing more than a pest that should be wiped out. In attempts to beautify their yards, people employ various poisons, strategically chosen plants, and gardening techniques. Success is attained when no trace of slugs can be found, although the worn-out gardener still watches and waits for their return, as completely ridding a garden of slugs is almost impossible. Experts, however, have discovered that the slug's evil reputation as an enemy of home gardeners may, in fact, be groundless to some degree. Although it is true that a slug can devour[ garden plants from the roots up in amazing quantities, it also produces nutrients for the soil, which help other plants grow. The diet of a slug consists of plant waste and mould, as well as living plants, making it a sort of natural recycling center. The unique structure of a slug digestive system enables it to take these discarded products, transform them into the nutrients that plants need, and then release those nutrients harmlessly as wastes. To some, this situation is unacceptable. No gardener wants to sacrifice his or her plants just to gain a few nutrients that could easily be provided by fertilizers In order to achieve a balance, both slug and gardener may have to compromise some things. One ly easy step is to separate plants with high slug appeal from those with low appeal. That way, the sections of the garden spared for plants with high slug appeal can contain plants that the gardener is willing to sacrifice so as to protect those plants that have a lower slug appeal . Another possibility is to leave some ground-covering plants in a less tidy state, since slugs particularly enjoy semi-decayed plant matter. The slugs will then be drawn toward this decaying matter instead of toward the living plants. These measures may seem slow and difficult but they are still preferable to commercial slug repellents for several reasons. The topsoil of a garden is often highly lacking in nutrients, due... Question: According to the passage, the wise way to deal with slug problem is that we should _ , Options: A: apply as many kinds of commercial repellents as possible to the plant roots B: sacrifice some plants and keep semi-decayed plant matter as food for slugs C: employ all possible gardening techniques to get rid of slugs completely D: protect the garden from slugs by keeping it in a clean and tidy state

I'm taking a test and have to guess the right answer to the question after the article. Article: About one million years ago, the Ice Age began. The Ice Age was a long period of time in which four great glaciers pushed southward to cover almost all the upper half of North America, and then melted away. Each glacier was a thick sheet of ice and snow that spread out from a center near what is now Hudson Bay in Canada. The winters were long, and the cool summers were too short to melt much of the ice and snow. The ever-growing sheet built up to a thickness of two miles at its center. As all glaciers do, these great glaciers slid. They pushed down giant trees in their paths and scraped the earth bare of soil. Many animals moved farther south to escape. Others stayed and were destroyed. When winters of little snow came, the summer cut into the edges of the ice sheets. As the glaciers melted, rocks soil and other things that had mixed with the ice and snow were left. New hills, lakes and rivers were formed. The last of the great glaciers began its melting about 11, 000 years ago. Its melting formed the Great Lakes. These lakes today are little changed from their early sizes and shapes. The largest of the North American river systems was also influenced by the glaciers. This is the Mississippi-Missouri-Ohio system. These rivers were miles wide at first. Through the years they settled into _ present channels. Question: In the last sentence, the word "their" refers to _ . Options: A: lakes B: rivers C: glaciers D: systems
