What is the purpose of the example of ozone data given in paragraph 2?

The findings were at first greeted by the scientific community with scepticism, as the British Antarctic Survey was not yet an established scientific community.

Moreover, it was generally believed that satellites would have picked up such ozone losses if they were indeed occurring.

• to show that NASA's Goddard Space Flight Center used unreliable methods of gathering scientific data

• to show how data gathering methods and the status of scientists may affect the way data is regarded

• to prove that it is wrong to dismiss evidence which comes from a non-established source

• to show how NASA and the British Antarctic Survey disagreed over the correct way to gather ozone data.

Where in paragraph 2 does this sentence best fit?

This was because of the way their computers had been programmed to discard any readings which appeared anomalous.

• (1) The findings were at first greeted by the scientific community with scepticism, as the British Antarctic Survey was not yet an established scientific community.

• (2) Moreover, it was generally believed that satellites would have picked up such ozone losses if they were indeed occurring.

• (3) It was not until the methodology of NASA's Goddard Space Flight Center was reviewed that it became apparent that data had been overlooked.

• (4) at the end of the paragraph

Consequently, scientists tend to believe they are not in a position to bear universal truths but to reveal tendencies.

However, [this] is countered by two factors.

• the scientific method and its inherent problems.

• the belief that scientists cannot reveal universal truths.

• the variation in scientific results under different circumstances.

• the list of factors which influence scientific research.
