I'm going to guess Boo Radley.
"By choosing a typeface that we feel the average user could read we'd be consciously alienating a section of our users. Instead, by selecting a typeface which is workable for those who struggle to read, we arrive at a choice that works for everyone. This is efficient and effective inclusive design."
The answer is <em>C: twisting the handlebars quickly and wiggling the front wheel</em>.
1. Twisting the handlebars quickly: "There is a third movement of the handle bars --a quick twist in the direction the machine is leaning if about to fall."
2. Wiggling the front wheel: [prevent the fall by throwing the balance the other way] " a similar result is accomplished by wiggling the front wheel...a continuous wiggle --changing the balance...-- is necessary to keep it upright."
That would be 9 dogs
12 x 0.25 = 3
12 - 3 = 9
