Discussion
Assertion: annotation must be scaled up when a drawing is to be plotted at a reduction. Reason: the plot reduces every drawn length by the same factor.
Answer: D
Correct answer: both the assertion and the reason are true and the reason explains the assertion
Both are true and the reason gives the mechanism. Plotting at 1:50 divides every drawn length by fifty, and annotation is drawn in the same space as the geometry, so it is reduced with everything else. Text intended to finish 3 mm high must therefore be drawn 150 mm high, and the same factor applies to arrowheads and hatch spacing.
