Lin is now a senior scientist of geophysics at Woods Hole Oceanographic Institution, in Massachusetts, where he spends his time studying not the scurrying of small animals and
fluctuating electrical current between trees (another fabled warning sign), but seismometer
readings, GPS coordinates, and global earthquake-notification reports.
What is the purpose for including these lines?
A
The lines show that Lin is untrustworthy as an expert because he relies on his
past experiences to identify earthquakes.
B
The lines show that Lin is an expert in the field who follows scientific methods
of research - modifying his methods of observing earthquakes - which
therefore builds credibility and trust for the reader.
С
The lines help create emotional appeal because Lin changed his
understanding about the causes of earthquakes.
D
The lines help create a feeling of trust between the author and readers,
because Lin disagreed with his co-researcher on the measurement of
earthquakes and the author was willing to share this with readers.
