Explanation:

Step1: Analyze one - fourth of pie chart

One - fourth is 25% of the pie chart. By visually inspecting the pie chart, News seems to take up approximately 25% of the pie.

Step2: Estimate percentage of Other and Drama

By visually estimating the sizes of the Other and Drama sectors in the pie chart, Other seems to be about 10% and Drama about 20%, so together they are approximately 30%.

Step3: Calculate percentage of Other given Documentary

If Documentary is 15% and we assume the whole pie is 100%, and by visually comparing the relative sizes of the Other and Documentary sectors in the pie chart, Other is approximately 5%.

Answer:

(a) News
(b) 30
(c) 5%
