Two hazardous conditions are radiation and small debris and u can use gold to reflect the uv radiation and u can use strong metals to prevent debris from damaging the shuttle.
Space travellers or astronauts may have to face hazardous health conditions like hypothermia due to the absence of heat.
Meteor showers can also cause a serious threat to the spacecraft and the astronauts in it.
<u>Explanation:</u>
When space travellers or astronauts are on a long space mission, they are vulnerable to a number of health hazards.
Hypothermia (death due to freezing) and meteor showers are the ones that can cause the greatest damage to life and property in the space.
To protect the astronauts from hypothermia, the spacecraft needs to be equipped with proper insulation so that the spacecraft doesn't stand vulnerable to temperature drops.
To protect the astronauts from meteor showers, the spacecraft should be equipped with the most advanced sensors and engines with a powerful thrust capable enough to allow the spacecraft to change its path quickly.
More recently, aerial photographs have often been taken from fixed-wing aircraft and today can even be taken from unmanned aerial vehicles (also knowns as drones).
I believe C is the correct answer; parent material is rich in nutrients for plants, and decomposed plant litter is also known as decaying organic material. Hope this helps! :)
