Answer: The spondee, a substitute foot, has 2 accents.
Step-by-step explanation: The spondee is a metrical foot used in poetry that has two long stressed syllables, that is to say the emphasis is placed in two syllables. It is also considered a substitute foot because instead of providing the metrical pattern in a poem, the spondee generally replaces another foot (another substitute foot is the pyrrhic). Moreover, two spondee examples are the words "earthquake" and "handshake".
