Final answer:
Shen Zhou used different kinds of brushstrokes and multiple colors of ink in his paintings, making option 4. Shen Zhou used many colors of ink to emphasize the variety he saw in nature as the correct answer.
Step-by-step explanation:
The question refers to the artistic conventions used by the Chinese artist Shen Zhou, one of the notable figures in Chinese painting during the Ming Dynasty. Shen Zhou is renowned for his contribution to the development of the Wu School style and his integration of strong brushwork, calligraphy, and poetry into his ink paintings. Specifically, Shen Zhou did not depict human figures with exaggerated proportions or make them larger to emphasize human dominance over nature, which negates options 1 and 2.
Instead, he is known for using various brushstrokes and incorporating color into his ink paintings, as observed in his works such as 'Poetic Feeling of Fallen Flowers.' Therefore, the most accurate convention to associate with Shen Zhou would be his use of different kinds of brushstrokes and multiple colors of ink to reflect the diversity he perceived in the natural world, making option 4 the correct choice.
