Explanation:

(b)

Step1: Identify 2016 gold bar

The gold bar (Camel Back) in 2016: total height (8) minus blue (Bald Mountain, 5).

Step2: Calculate height

$8 - 5 = 3$

Step1: Find 2018 Bald (blue) and total

Bald (blue) in 2018: 3. Total in 2018: blue (3) + gold (3) = 6.

Step2: Calculate percentage

$\frac{3}{6} \times 100 = 50$
