Hi I am a registered student and am going through Lab # 3 on critical reasoning diagramming. I got to solution #18 and at 3:04 min the explanation stalled and wont' continue. Is there a malfunction in that lab? For quick reference, could you just give me the answer as to what were labelled as the conclusion and premises of that particular argument.

Two things:
- please contact tech support to see if they can resolve the problem for you (and / or ensure that it doesn't happen again): techsupport@manhattangmat.com or 800.576.GMAT during business hours

- to answer your question:
1 P Proposed ordinance req installation in new homes of sprinklers automatically triggered by fire
2 P Home builder: > 90% of residential fires are extinguished by household member
3 C Residential sprinklers only marginally decrease prop damage caused by residential fires

But definitely contact tech support so you can watch the rest of the lab!
