Read the following passage about and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions.

If nanotechnology sounds too far-fetched, looking at what geckos can do might be a good starting point. These lizards could quickly snatch the champion title in a climbing competition should there be one. Watching them climb upside down on a horizontal pane of glass, one can't help thinking that spiderman should really have been called geckoman. Without breaking a sweat, they can easily hang from a single toe, and they do so by pure adhesion, not by sticking a toe in a hole or by curling it around something they can grip. Scientists estimate that if all its toes touch the glass, it could take the weight of a 100kg person suspended below it, of course, under the condition that the rest of the body were strong enough. Although each toe is equipped with a tiny hook-like claw at the end, these are almost useless on the glass. The secret to geckos' superpower lies in the amazing structure of the skin of their toes.
