Answer:
The correct answer is: infrared thermometers, protective clothing, and improved prosthetic limbs
Explanation:
Although it is hard to determine which of these inventions were a result of research and development specifically designed for space travel, it is safe to proceed with exclusions, by keeping in mind that space travel has been possible only since the mid-1900s:
- Computers, the stethoscope, and the microscope is not correct, as computers were created much earlier in the last century, stethoscopes were invented in the early 1800s and microscopes have been around since the 1600s.
- Heating pads (early 1900s), cooling beds, and radiation-monitoring devices (early 1900s) is also to exclude.
- Pharmaceuticals, medical devices, and diabetic supplies have been for centuries.
