<p>This site is a wonderful resource, but it remains that it is good to remind everyone how easy is to find a number of suggested answers. Be it here in the archives or in outside blogs and websites. </p>
<p>Here’s an example of such answers:</p>
<p>I merely googled Practice Test 4, Section 6, #8 and got this withing a few seconds:</p>
<p>[TestTakers</a> Blue Book Blog: Test 4 Section 6 - #8 (page 595)](<a href=“http://bbb.ttprep.com/2009/12/test-4-section-6-8-page-595.html]TestTakers”>TestTakers Blue Book Blog: Test 4 Section 6 - #8 (page 595))</p>
<p>It beats looking the problem in the blue book! And, most importantly, it helps to check different approaches until one clicks in the head. Every problem has different approaches to the same answer, but one is usually faster for a strong student. This problem is no different.</p>
<p>PS To be clear what I suggest is to google the questions, find a couple of suggestions, and then … come here to discuss and verify the validity of the suggested answers. There are gems out there, but also a lot of garbage. For instance, many answers on “ask yahoo” are plain wrong as the one-eyed leads the blind.</p>
