Which could be the best title for this passage?
Sometimes it feels like the Internet has the answer to
everything. At our fingertips, we have the ability to
improve our knowledge or test someone's doubtful "Did
you know...?" statement. Our online searches have their
limits, though. If we have questions about what is in
front of us, the Internet cannot always help. Is this water
safe to drink? How much fat is really in this steak?
Search engines cannot access these objects, so their
answers are limited to averages and tendencies. To get
real answers, we must tap into the chemical make-up of
our world. The technology to do this exists, but it is
limited to immovable pieces of lab kit called
near-infrared (NIR) spectrometers. NIR spectrometers
work by shining a spectrum of near-infrared light onto
objects and analysing the light that bounces back. Say
you want to scan an apple. Each substance within the
fruit, be it water, sugar, or fibre, will respond to the light
in a unique way. The bonds within them will be
energised, moving around at specific wavelengths. The
spectrometer can detect these wavelengths and
then identify what is inside your particular apple. NIR
light is also perfectly safe to use, unlike more
destructive X-rays or ultraviolet radiation
