What is the content of q after assigning the eval to it? As you have
described it I would have expected that to generate a runtime error:
1.8.7-p374 :003 > question ="... from a light source is equal to the
<a> href='www.somewhere.com'>index of refraction</a> (n) divided by
the distance (in meters) of the light rays..."
=> "... from a light source is equal to the <a>
href='www.somewhere.com'>index of refraction</a> (n) divided by the
distance (in meters) of the light rays..."
1.8.7-p374 :004 > eval(question)
SyntaxError: (eval):1:in `irb_binding': compile error
(eval):1: syntax error, unexpected tDOT3
... from a light source is equal ...
