(Question)
The richest man in the world can now also claim a degree from the college he dropped out of three decades ago. Microsoft Chairman Bill Gates delivered the commencement   address at Harvard University on Thursday, and was awarded the L. L. D. honorary doctorate  . "Our speaker is known as the most influential entrepreneur  of the personal computer revolution. He was named as one of the 100 most influential people in the world in 2004, 2005, 2006 and again in 2007, " said Harvard's president, Derek Bok. Then Bok spoke more directly to Gates: "Just think what you could have achieved if you had stayed another two years." Gates told the students, many of whom will soon be launching into full-time careers, that work isn't the only thing of importance. "Judge yourself not on the professional accomplishments but on how well you have addressed the world's inequities, how you have treated people who have nothing to do with you," he said. In recent months, Gates has been giving a larger part of his time and energy to the Bill & Melinda Gates Foundation, which focuses on issues including global health and education. In 2008, he plans to make the foundation his chief responsibility. But for the most part, the Microsoft co-founder stuck to the serious message about trying to make the world a better place.

Question: Owls  are some of the world's greatest hunters. From head to feet, owls' bodies are built to hunt. Scientists are studying all the things that make owls such great hunters. Most owls hunt at night. The birds have excellent hearing, which helps them find their next meal in the dark. Owls have one ear that is larger and set higher than the other. When an owl hears a sound, it listens closely. Is the sound lounder in its right ear or left ear? Does the upper or lower ear detect the sound first? The information helps the owl find the location of its prey without ever seeing it. Owls don't depend just on their hearing to hunt. After a sound draws an owl's attention, it zeroes in with sight. Many birds have eyes on either side of their heads. But an owl's eyes face forward, like a person's. Images from each eye combine to form a 3-D picture, similar to how we see. That helps owls better judge a prey's size, distance, and speed. An owl's eyes are so large that they can gather lots of light. That helps the owl see better when hunting at night. An owl's eyes are also fixed in their sockets . It can't roll them like we can. Instead, an owl keeps prey in its sight by turning its head. Owls can move their beads nearly upside down and turn them 270 degrees around. Their necks have 14 vertebrae . That's twice as many neck bones as a person has. The blood vessels  thread through holes in an owl's vertebrae. The researchers found that these holes are very large so that the extra space provides an air cushion that protects the vessels. Detecting prey is only the first step for owls. Next they must catch their meals. An owl can fly inches over your head and you can't hear anything. The secret to owls' silent flight is their feathers. Fine "hairs" cover the surface of an owl's wing feathers. And the feathers' edges have soft barbs . Together, they make the sound of air rushing over the owl's wings quieter and less clear. The shortcoming of an owl's fixed eyes can be made up by its  _  . A) large head B) strong legs C) body size D) flexible neck
Answer:
D
