Recognition of Community Members by Ants

Ants have a remarkable ability to recognize and distinguish members of their own community from outsiders, even after being separated for a long period of time. The author conducted experiments to test this recognition and found some interesting results.

Anecdote of Inebriated Ants

- The author intoxicated a group of ants from different nests and observed their behavior.
- The ants from the same nest as the intoxicated ones recognized them and carried them back to the nest.
- This behavior indicates that ants have a strong recognition of their community members, even when they are unable to give any signs or passwords.

Explanation of the Answer

The anecdotes of the inebriated ants do support the induction that ants recognize their comrades by a mysterious password. The experiment showed that even when the ants were intoxicated and unable to communicate in a conventional way, their fellow ants from the same nest still recognized them and helped them back to the nest. This suggests that ants have an innate recognition system that goes beyond simple signs or passwords, allowing them to identify and differentiate their community members from outsiders.

The advent of vaccines has led to a dramatic rise in the quality of life in the 20th century. Vaccines have reduced morbidity of diphtheria, mumps, polio, and several other diseases by over 99%. In the wake of such overwhelming success, many government policies have moved to make vaccines mandatory, but many libertarians and conservatives have argued that this infringes on the individual right to his or her body. However, I believe that mandatory vaccines may in fact protect rights.When evaluating individual rights, the quote The right to swing my fist ends where the other mans nose begins is important to consider. Does the right to choose whether or not to vaccinate harm other individuals? In the sense that you enable yourself to transmit disease to unvaccinated individuals, yes.The problem with this logic falls in the concept of herd immunity. Herd immunity is when such a large percentage of a population is immune to a disease that, even if one susceptible person becomes ill, the disease is unlikely to spread. For example, if 96% of a population has received ameasles vaccine, when one individual gets measles, it is unlikely that they confer the disease to the other 4% of people, because the individual is surrounded by so many who are immune.These individuals arent all free riders either. Vaccines are not 100% effective, they cannot be used on people of all ages, and some people are allergic to them. These individuals did not make a conscious choice to be vulnerable to a disease, and by one person choosing not to vaccinate, their herd immunity is weakened, significantly increasing their risk of becoming sick.This has happened several times before, particularly after Andrew Wakefields false autism link. In 2014, a measles outbreak occurred in California, only 45% of measles cases occurred in unvaccinated individuals, and among those 12 were in infants too young to be vaccinated.In defending mandatory vaccines, I have been asked if this same argument could be applied to justify gun control. While the data is conflicting depending how its looked at, even if there is a link between gun ownership and gun violence, I dont believe that the increased risk associated with gun ownership is not grounds considering it a right infringement. With guns, the decision that puts others in harms way is not the decision to purchase, but the decision to fire. Furthermore, the decision to fire is already controlled by the illegality of assault, manslaughter, and murder, while the decision not to vaccinate cannot be controlled by anything other than laws mandating it.Vaccines are one of the most important health advancements of the 20th century, but there are many people that they cannot directly protect. For this reason, it is critical that we prevent healthy adults from making a choice not to vaccinate.Q.Which of the following if true would strengthen the authors argument?
