Question 2 of 10 Which technology resulted from engineers observing the structure of a cheetah's back legs? A. Hook-and-loop fasteners B. More efficient solar cells C. Improved prosthetic limbs D. Faster high-speec I trains

## Step 1<br />The question is asking about the technology that was developed as a result of engineers observing the structure of a cheetah's back legs. The options provided are: A. Hook-and-loop fasteners, B. More efficient solar cells, C. Improved prosthetic limbs, and D. Faster high-speed trains.<br /><br />## Step cheetah's back legs are known for their speed and agility, which have inspired engineers to develop improved prosthetic limbs. These limbs are designed to mimic the speed and agility of a cheetah's legs, allowing for faster and more efficient movement.<br /><br />## Step 3<br />The other options, such as hook-and-loop fasteners, more efficient solar cells, and faster high-speed trains, are not directly related to the structure of a cheetah's back legs.
