PG problem file Explanation

Problem tagging data

Problem tagging:

DOCUMENT();

loadMacros(
"PGstandard.pl",
"MathObjects.pl",
"AnswerFormatHelp.pl",
"PGcourse.pl",
);
TEXT(beginproblem());

Initialization:

Context("Numeric");

$slideshow = MODES(
HTML=> 
"<iframe src='https://docs.google.com/presentation/d/1pk0FxsamBuZsVh1WGGmHGEb5AlfC68KUlz7zRRIYAUg/embed#slide=id.i0'
frameborder='0' width='555' height='451'></iframe>", 
TeX =>
"An embedded Google slide show."
);

$video = MODES(
HTML=> 
'<iframe width="420" height="315" src="//www.youtube.com/embed/NpDXXjClErk" 
frameborder="0" allowfullscreen></iframe>', 
TeX =>
"An embedded YouTube video."
);

Setup: We create a mode dependent variable $slideshow that displays a Google slideshow inside an html iframe when in html mode, and the message "An embedded Google slide show." in TeX mode. If you omit the TeX mode stuff, then there will be errors when the pdf hardcopy is generated. Similarly for the $video. (Searching the web for "YouTube embed video" should bring up instructions for how to get the code to embed a YouTube video into a webpage.)
