B) contextual
Explanation:
Contextual advertising is a form of targeted advertising for advertisements appearing on websites or other media.
For example:
Timothy was reading tournament results of the football World Cup matches on Infogoalistic.com. As he was going through the results, an advertisement of new football studs popped up. This is an example of <u>contextual</u> advertising.
The *image* tag is used to bring an image on the website.

<u>a. The scientists must be careful of how many variables they include in their simulation so they do not cause further harm to the frogs.</u>
Explanation:
It is not statistically accurate to assume that the number of variables included in the simulation would cause further harm to the frogs because we need to <em>remember </em>that a simulation is simply a computerized imitation of a real situation, which is usually not totally alike with a real process.
So in no way from a statistical standpoint, does the scientists' decision on the number of variables causes direct harm to the frogs.
