What is an important step to remember with skimming and scanning?

a) use a highlighter to mark the parts of the text you want to read later.
b) go back and read the text. you will miss important details if all you do is skim and scan.
c) if all the text is the same color there is no way to scan for specific information.
d) always look for graphics first. if there are no pictures, charts, or maps, go back to the beginning and start scanning.
