If poster colour repeatedly leaves streaks on paper what should be checked first?

Correct answer: Brush moisture and paint consistency

The governing concept is diagnosing application quality by checking the brush and mixture first. A brush that is too dry may drag instead of laying down a continuous stroke, while paint that is too thick or unevenly mixed may spread irregularly. Thus option B is correct. The title, paper length and palette colour do not normally cause repeated streaks; they are unrelated to the paint-transfer process.
