Final answer:
Artists often deal with making their artwork relevant and capturing inspiration, which are true issues. Complete personal control is usually desired, not a problem, and artists are not bored by lack of complaints, so both are false.
Step-by-step explanation:
When examining the challenges faced by artists, it's important to acknowledge the complexity and nuances of artistic creation. Artists often have to find a balance between staying true to their vision while making their artwork relevant to their audience and the cultural context. This delicate balance is a common issue they encounter. However, artists typically strive for personal expression and control over their work. Hence, a statement that artists face the problem of being allowed complete personal control over the content and purpose of their artwork is false. In fact, having creative freedom is usually seen as a fundamental aspect of being an artist, even though this can come with its own set of challenges, such as the need for financial support or public understanding. The idea that artists are bored because nobody ever complains about their artwork is also false. Feedback, whether positive or negative, is an essential part of artistic growth and public engagement. Therefore, statements (a) and (c) are generally considered true, while statements (b) and (d) are false.
