As much as 25 percent of the fruits and vegetables grown in chinese agricultural regions rot before they can be transported the long distances to market. which of the following is a smaller, more manageable problem that contributes to this complex problem?
a. conserving earth's limited fossil fuel reserves
b. reducing global emissions of greenhouse gases
c. developing effective methods of food preservation
d. preventing extinction of endangered species

The answer is letter C, Developing effective methods of food preservation.

Explanation:

The question above is asking for a smaller, more manageable way to control the complex problem of the fruits and vegetables rotting before they reach the market.

Among the choices, letter C is the only smaller and manageable way that can be done. Chinese farmers and the agricultural sector could develop ways to preserve their fruits and vegetables, without rotting for some days, so it can still be fresh when transported to the market. Food preservation method will depend on the weather condition in that area. For example, during hot weather, the foods may be preserved by canning them or turning them into jams and jellies. In this way, they can earn some income rather than allowing the food to rot and go to waste.

When it comes to apples, "freeze drying" is an effective method to preserve them. This allows the fruit to be frozen in vacuum container and prevents it from coming in contact with water, as well as oxygen. These substance and elements can cause fast rotting or browning of fruits.

Developing effective methods of food preservation

Explanation:

Ensuring Food preservation is a deliberate step towards preventing the greater global problem of food shortage. Loss of 25% of agro produce of fruits and vegetables is significant enough to signal the possibility of food shortage in areas that depend on China for regular supply of fruits and vegetables.

Hence paying attention to food preservation may mitigate against the global crisis of food shortage and consequent hunger and starvation.

Efficient means of food storage must be developed to help solve this problem. Developing these systems is quite a smaller problem compared to that of food shortage.

Food stored by better storage means arrives the target market in good condition

the rocks are classified by the geological process they are formed by. the three main groups of rocks are igneous, metamorphic, and sedimentary. minerals are not they are classified under the chemical classes they are in. these groups include silicates, sulfates and carbonates.
