Final answer:
A manifesto is a public declaration of a group's or individual's central ideas, which is true. Historical examples include The Communist Manifesto by Marx and Engels, and the Futurist Manifesto by F.T. Marinetti. The Ostend Manifesto was a diplomatic communication regarding the acquisition of Cuba by the United States.
Step-by-step explanation:
True. A manifesto is indeed a document that publicly declares the key principles, aims, and intentions of a group or individual. Manifestos play a significant role in various aspects of society, including politics, art, and social movements. For example, Karl Marx and Friedrich Engels’s The Communist Manifesto in 1848 set forth the goals of the communist movement. Another example is the Futurist Manifesto, written by F.T. Marinetti in 1909, which announced the principles of the Futurism art movement, advocating for the rejection of traditional values in favor of modernity and technological progress. Manifestos such as these have historically been used to articulate visions for change and to rally support around a shared set of ideas or goals.
In contrast to the accurate characterization of a manifesto, the Ostend Manifesto mentioned in the Test Yourself section was a diplomatic dispatch that suggested the United States should acquire Cuba from Spain to protect American interests, not an agreement to free oppressed Cubans as one might misconstrue from the provided options.
