We should consider if medical situation has been ruled out.

Based on my research, the best answer here is answer C: partial evaluations may provide a description of the costs, or consequences, of competing alternatives. This is basically the first step in researching which drug therapy would be best for a certain situation.

A full evaluation should be done, but this might be enough to eliminate something as too expensive or too risky. I must repeat: it might be enough to eliminate an option. If a partial evaluation only looks at the costs and consequences, it would be worth it to look into side effects of the drugs as well, which a full evaluation may take into account.

This is a good place to start, but more research should be done, even into the ones you may not use.

The hollow stem of a blade of grass is called a culm. They are rarely branched above the ground. The second half of the leaf then opens out into the leaf blade. But there is more to this in plant physiology. There are four main parts to a grass plant, the roots, the stem or culm, the leaves and flowerhead which is properly called, inflorescence.

You can go further and examine each part for its diagnostic features. These help in correct identification. In complex cases, the combination of several characters can lead to the correct name.

The white structure shown here is a ligule. This is the structure which clasps the stem at the junction of blade and sheath. Ligules, being outgrowths from the sheath vary in size, shape, and texture, so they are useful in the identification process. Ligules may be scalloped, rounded, tapered, edged with hairs, for instance, and I have not mentioned all the possibilities.

The ligule is a projection at the base of the leaf blade in the grass family, and is actually a small membrane that extends up the stem of a grass from where the leaf blade separates from the sheath. On the diagram shown in the question, the ligule is white and suggests it might be edible. It will have moisture but not as much as within the stem as a whole.

The sheath around the stem, as shown in this diagram, is a whitish membranous sheath called an ocrea. The cosmopolitan family, Polygonaceae, can be recognized immediately by the presence of the ocrea. This family contains around 1000 herbs, shrubs, climbers and a few trees. Characteristic of each of these is that the base of each leaf forms a sheath around the stem at the stalk attachment point.

Some members of this family are popular and useful, like rhubarb. Some are pernicious and hated by gardeners for their resistance to removal and eradication like Japanese knotweed. This one might almost be called the criminal within the Polygonaceae genus.

The answer to this question is A. You can look at the illustration to know what the answer should be. Some people hate anything that has to do with math. At times, they do not even understand why there is a need to learn how to measure different angles and also points and lines. Angles are generally present in our daily lives, although we may not always realize it.

There are also some professionals who are aware that they should always use angles and that everything should be precise; otherwise, they may start to encounter further problems in the long run. The use of the right tools can help measure angles easier.
