+#1) What is your favorite Ruby class/library or method and why?
+I like Ruby in all. Some awesome points: Blocks/Lambdas, "Everything is an Object", Metaprogramming, etc.
+---------------
+
+#2) Given HTML: "<div class="images"><img src="/pic.jpg"></div>" Using Nokogiri how would you select the src attribute from the image? Show me two different ways to do that correctly the the HTML given.
+document = Nokogiri::HTML(open("http://lalala.com/"))
+document.at_css('.images img').attr('src')
+#or
+document.xpath('//div[@class="images"]/img/@src').map {|s| s.value }
+---------------
+
+#  3) If found HTML was a collection of li tags within a div with class="attr", how would you use Nokogiri to collect that information into one array?
+document.xpath('//li[@class="attr"]').map {|li| li.value }
