Read this excerpt from "Herd about the Flu."
What is the main idea presented in this excerpt?
The flu shot helps prevent huge numbers of infections. Even
when it doesn't fully prevent infection in every person, the
shot makes any flu infection less serious. On a global scale,
the vaccine can reduce the number of infections only if most
people in the community take it. That's because vaccines
need to reach enough people to achieve a "herd immunity,"
the level of immunity needed to prevent the virus from
spreading. If too few people get the vaccine, the people who
receive it may not be well protected against infection.
So the next time you are at the drugstore, and you see No
Flu Shots Available, think about the reasons behind it. Drug
makers are scared to make too many flu shots because
they could lose too much money. They then make fewer flu
shots and the effect of the flu shots becomes weaker
because not enough people take it. People become more
reluctant to take the flu shot since they don't think it will fully
As fewer people get the flu virus, the flu shot becomes
less and less useful.
O As fewer people get the flu virus, the flu shot becomes
more and more useful.
O As fewer people get the flu shot, it becomes more
effective, but as more people get it, the flu shot becomes
less effective.
O As fewer people get the flu shot, it becomes less
effective, but as more people get it, the flu shot becomes
more effective.

are you asking for an essay and whats the story?

1. drag the central argument paine presents and its two claims to complete the chart. argument claims america may have flourished more had it not been under the power of any european country. america may have flourished under britain in the past, but there is no guarantee that it will continue to flourish in the future. america will continue to flourish as long as the essential food products it sells are bought and eaten in europe. the american colonies will no longer flourish when britain makes war against them. britain's king has shown himself to be prejudiced against the colonies, rather than wanting them to flourish.

2.select the sentence in this passage that can be classified as a false statement.

although few humans per year are attacked by polar bears, any individual attack can be terrifying and even fatal. the warming of arctic regions has allowed the intrusion of humans into the polar bears’ habitat, increasing the danger of harmful contacts. remaining alert and using precautions can humans avoid a negative encounter with a polar bear. traveling together and staying close to the group can humans avoid bear attacks. certain weapons, including nonlethal ones such as pepper spray, are effective against polar bears. once a bear has decided to attack, however, nothing can be done.

3.select the sentence in this passage that demonstrates the fallacy of making an extreme either-or claim.

the civil war was the bloodiest conflict in the history of the united states. more than 600,000 soldiers lost their lives. the fighting took place in many different cities and throughout the countryside. the wounded often suffered acute pain while in the field hospitals. they all should have asked for better care. william hammond, the surgeon general of the union army, created a new system of sanitary field care. if people do not accept hammond as the most important person from the civil war, they have no understanding of the war.
