What does "raise the income" refer to in relation to financial support?

"Raise the income" specifically refers to actions or strategies aimed at increasing the overall earnings or revenue, which aligns directly with increasing financial support. Boosting the income can involve various methods such as enhancing productivity, seeking additional revenue streams, or implementing strategies that lead to higher sales or profits. This concept is essential in understanding how organizations and individuals can improve their financial standing and sustain their operations.

The other options do not accurately reflect the intent of "raising the income." Decreasing the income would lead to less financial support, maintaining the income level implies there would be no change, and eliminating all expenses does not relate directly to increasing income. Instead, it focuses on cutting costs, which, while helpful in some contexts, does not inherently raise income itself.
