I looked this question up and found that there should be a website address right after "Underground Railroad.” World Book Online. 2012. Web. 20 December 2012.

It contains the word "worldbookonline", but I will not post the whole thing here so that will not interpret it as a link to an external website. However, this information is important for us to find the correct answer.

The option that best describes the two citations is:

C. The two citations provide information on how to locate the sources.

Explanation:

Both citations make it clear what type of source was used - print or digital. For the first one, we get to know the publisher's name and the year, which makes it easier to locate. For the second one, we are given the link to the website where it can be found so that we too can access it. Therefore, both citations provide information that helps us locate the sources.

The correct answer is any groups they thought threatened Catholicism.

The participants of the Fourth Crusade, financed by Venetian merchants, when they arrived in Constantinople, sacked the city and invaded the churches to remove the valuables.

The looting caused the weakening of Constantinople's trade and the strengthening of cities on the Italian peninsula, which began to monopolize the spice trade in the Mediterranean.

Although they did not fully achieve their religious objective, the Crusades promoted major changes across Europe, such as the reopening of the Mediterranean to European shipping and trade. This made it possible to intensify trade between the West and the East, which was largely interrupted by the Muslim expansion.
