Learning about the benefits of preventative healthcare can be particularly
difficult. Check all of the reasons below why this may be the case.

[x] A large amount of time passes between undertaking a preventative measure
and seeing the result.
[ ] Non-immunized people will always fall sick.
[x] If others are immunized, fewer people will fall sick regardless of a
particular individual's choice to get immunized or not.
[x] Trust in healthcare professionals and government officials is fragile.

[explanation]
People who are not immunized against a disease may still not fall sick from
the disease. If someone is trying to learn whether or not preventative measures
against the disease have any impact, he or she may see these people and conclude,
since they have remained healthy despite not being immunized, that immunizations
have no effect. Consequently, he or she would tend to believe that immunization
(or other preventative measures) have fewer benefits than they actually do.

Lateral inhibition, as was first discovered in the horsehoe crab:

( ) is a property of touch sensation, referring to the ability of crabs to
detect nearby predators.
( ) is a property of hearing, referring to the ability of crabs to detect
low frequency noises.
(x) is a property of vision, referring to the ability of crabs eyes to
enhance contrasts.
( ) has to do with the ability of crabs to use sonar to detect fellow horseshoe
crabs nearby.
( ) has to do with a weighting system in the crabs skeleton that allows it to
balance in turbulent water.

[Explanation]
Horseshoe crabs were essential to the discovery of lateral inhibition, a property of
vision present in horseshoe crabs as well as humans, that enables enhancement of
contrast at edges of objects as was demonstrated in class. In 1967, Haldan Hartline
received the Nobel prize for his research on vision and in particular his research
investigating lateral inhibition using horseshoe crabs.

What is the technical term that refers to the fact that, when enough people
sleep under a bednet, the disease may altogether disappear?
= herd immunity

[explanation]
The correct answer is herd immunity. As more and more people use bednets,
the risk of malaria begins to fall for everyone – users and non-users alike.
This can fall to such a low probability that malaria is effectively eradicated
from the group (even when the group does not have 100% bednet coverage).
[explanation]

### 區分大小寫字母與文字輸入題型¶

By default, text input problems do not require a case sensitive response. You can change this and require a case sensitive answer.

To make a text input response case sensitive, you must use the 進階編輯模式.

In the advanced editor, you see that the type attribute of the stringresponse element equals ci, for case insensitive. For example:

<stringresponse answer="Michigan" type="ci">
<textline size="20"/>
</stringresponse>

To make the response case sensitive, change the value of the type attribute to cs.

<stringresponse answer="Michigan" type="cs">
<textline size="20"/>
</stringresponse>

### 文字輸入題型的文字長度設定¶

If the default response field length is not sufficient, you can change it using the 進階編輯模式.

<stringresponse answer="Democratic Republic of the Congo" type="ci">
<textline size="20"/>
</stringresponse>

To change the response field length, change the value of the size attribute:

<stringresponse answer="Democratic Republic of the Congo" type="ci">
<textline size="40"/>
</stringresponse>
