To engage your audience using the Point A slide on the upper left in Figure 7-7, try one of the oldest and simplest techniques to prompt interaction: ask a question. Sketch a question mark on the chart. The Point A headline is Your returns will stay at if you do nothing. When you show this slide to a smaller group, ask an open-ended question such as, Do you agree or disagree with that and then have a conversation about it. When you show the slide to a larger audience, ask the question, How many of you agree with that and then hold up your hand to signal the audience to raise their hands. Quickly count the number of hands and tell the audience the results of the poll as you move on to the next point, It looks like about two-thirds of you agree. Well, today we re going to talk about . . . Taking a quick poll like this makes the audience feel like they re part of the conversation and also gives you a gauge of where the audience stands in relation to the topic. You can vary this technique with larger audiences by providing the audience with interactive polling devices, which some companies build speci cally for PowerPoint. When you ask the audience a question, the results of the poll are displayed directly on your Point A slide in the form of a chart that summarizes the polling results.

OS/2: http://hobbes.nmsu.edu/pub/os2/dev/misc/ruby-181.zip. BeOS: Ruby is installable in the same manner as with Linux, as described earlier. Linspire or Lindows: As a Linux distribution, you can use the same instructions as for Linux, earlier. Symbian Series 60: http://developer.symbian.com/main/tools/opensrc/ ruby/index.jsp. Java Virtual Machines (JVMs): http://jruby.codehaus.org/. Other Unix versions: Refer to Installing Ruby from Source Code in the preceding Linux section for instructions that are reasonably distribution generic. In many cases, the versions of Ruby for some operating systems might be out of date or unsupported. If this is the case, and you re confident about being able to compile your own version of Ruby directly from the Ruby source code, the source code is available to download from http://www.ruby-lang.org/en/20020102.html. To test that Ruby is installed sufficiently to continue with this book, you want to check which version of Ruby is installed by asking Ruby for its version, as follows:

In 3, you saw how you could use string formatting to format all the values in a tuple. If you use a dictionary (with only strings as keys) instead of a tuple, you can make the string formatting even snazzier. After the % character in each conversion specifier, you add a key (enclosed in parentheses), which is followed by the other specifier elements:

Next you need to get the middle third of the length-sorted sentences in sentences_sorted, as these are the ones you ve deemed to be probably the most interesting. To do this you can divide the length of the array by 3, to get the number of elements in a third, and then grab that number of elements from one third into the array (note that you grab one extra element to compensate for rounding caused by integer division). This is done like so:

So far, you ve focused on numbers and charts to start off strong with the nancial executives. If this approach is a match with your audience, another way to go is to sketch out a motif as it plays out over the Point A and Point B slides. If you chose to incorporate a motif through the headlines of your story template, now you ll extend this recurring theme from your written words to the sketches of your slides. For example, if you use

one_third = sentences_sorted.length / 3 ideal_sentences = sentences_sorted.slice(one_third, one_third + 1)

The first line takes the length of the array and divides it by 3 to get the quantity that is equal to a third of the array. The second line uses the slice method to cut out a section of the array to assign to ideal_sentences. In this case, assume that the sentences_sorted is 6 elements long. 6 divided by 3 is 2, so a third of the array is 2 elements long. The slice method then cuts from element 2 for 2 (plus 1) elements, so you effectively carve out elements 2, 3, and 4 (remember that array elements start counting from 0). This means you get the inner third of the ideal-lengthed sentences you wanted. The penultimate line checks to see if the sentence includes the word is or are, and only accepts each sentence if so:
