Read the passage. What does the author use to
engage the reader?
Why does the whole world measure its time and define its
position in relation to the Greenwich Meridian, a line
passing through a spot on the banks of the Thames in
south-east London? The story begins with the invention
in London of a sea-going clock that allowed sailors to find
their longitude. The object pictured here is one of those
clocks – a marine chronometer made around 1800 -
which could keep perfect time even in rolling seas.
