Question 8: Which of the following best summarises paragraph 2?

A. The introduction of Earth's microorganisms to Mars poses a serious technical hurdle for researchers, requiring the creation of more sophisticated sterilization methods to safeguard the planet's unique and original biological state.

B. Mission planners and scientists seem to accept terrestrial microbial contamination as a calculated trade-off, viewing the complication to the search for native life as a necessary price for establishing a human presence.

C. The definite contamination of Mars with terrestrial microbes will make the search for native life much harder, as future scientific instruments may struggle to differentiate between endemic and newly imported microorganisms.

D. The arrival of humans on Mars is certain to cause an irreversible biological contamination, a development that will permanently degrade the planet's pristine condition and impede the scientific quest for native organisms.
