There is no explanation for this question on 7sage, so I'll just post a discussion that includes my reasoning on how I got this wrong in timed conditions and later right in BR. If anyone finds it useful, great!
@sunnyp89 - the answers above nail it: more "kinds of lamps" does not explain "more lamps"
And please remove the verbatim question.
Maybe @"Dillon A. Wright" can help with editing out the copyrighted content. The question is PT36, S1, Q23

In Prep-Test 76 the system scored me wrong on S1 Q18, when my answer matches the solution table supplied with the prep-test and other online resources.
