Water quality testing would be the best approach.
Answer:
By 1795, the warrior chief, Kamehameha the Great, had conquered most of the Hawaiian islands and established a monarchy. In the 1820s, American whalers, traders, and Christian missionaries began to visit and settle in the kingdom of Hawaii.
Although a small minority, the Americans in Hawaii soon owned much of the land, which they began to turn into large sugar-cane plantations. The native Hawaiian population dropped sharply due to smallpox and other diseases that came with the American immigrants. Needing more workers, the sugar planters imported Chinese and Japanese contract laborers who agreed to work on the plantations for a set period of time.
As their influence increased, the Americans became deeply involved with the government of the Hawaiian kings. In 1840, American advisors helped King Kamehameha III produce Hawaii's first written constitution.
By 1842, the United States had developed regular diplomatic relations with Hawaii and supported its status as an independent country. After King David Kalakaua ascended the throne in 1874, Hawaii and the United States signed a trade agreement lifting some restrictions on exporting Hawaiian sugar to the United States. In addition, this agreement permitted the United States to lease a naval station at Pearl Harbor.

Answer:
It is an example of frequency-dependent selection. Due to several cheaters in the population, the fruiting body's stalk is not made properly. So, all individuals have lesser fitness.
Explanation:
Natural selection:
The population contains both superior as well as an inferior organism where natural resources are limiting so it will cause competition between organisms. As a result of competition, it will select superiors, and inferiors are deleted and they are given reproductive advantages. Due to this reproductive advantage new population emerges. It is more suitable for the environment.
Natural selection divides into three parts that are directional, disruptive, and stabilizing selection.
The given question is the example of frequency-dependent selection. Due to several cheaters in the population, the fruiting body's stalk is not made properly. So, all individuals have lesser fitness. Directional selection will not lead to fixation of cheater genotype. This is because cheating can be controlled through high relatedness in social groups, resulting from kin discrimination.
It is controlled through positive pleiotropy, where the cooperation gene has an additional vital function. Cheating will be controlled if stalk vs. spore is a result of environmental, not genetic factors. An example, spore fate can be a result of the position in the mitotic cell cycle.
