IELTS Reading: true, false, not given

Read the following passage about the ‘Beaufort scale’.

The Beaufort scale is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale, although it is a measure of wind speed and not of force in the scientific sense.

The scale was devised in 1805 by Francis Beaufort, an Irish Royal Navy officer. In the early 19th century, naval officers made regular weather observations, but there was no standard scale and so they could be very subjective. The initial scale of thirteen classes (zero to twelve) did not reference wind speed numbers but related qualitative wind conditions to effects on the sails of a frigate, then the main ship of the Royal Navy.

In 1916, to accommodate the growth of steam power, the descriptions were changed to how the sea, not the sails, behaved. The Beaufort scale was extended in 1946, when forces 13 to 17 were added. Today, hurricane force winds are sometimes described as Beaufort scale 12 to 16.

Are the following statements true, false or not given?

۱٫ The Beaufort scale is a scientific measure of wind force.
۲٫ In the early 1800s, naval officers demanded a more accurate way to measure weather conditions.
۳٫ The original scale measured the effect of wind on a ship’s sails.
۴٫ Today, the Beaufort scale is still the predominant scale for wind description.
