Final answer:
Consonance involves the repetition of consonant sounds at the end of words within a phrase. Without the specific phrase from "Opportunity," one can only provide a definition and a general example of consonance, such as 'the slithering snake shakes its little rattle.'
Step-by-step explanation:
The bold portions of the phrase from "Opportunity" that illustrate consonance appear to be missing from your question. However, consonance refers to the repetition of consonant sounds at the end of words. For example, in the phrase "the slithering snake shakes its little rattle," the repetition of the 's' consonant sound is an instance of consonance.
Similarly, the poem by Sarah Teasdale titled "There Come Soft Rains" is likely to contain examples of consonance, as well as alliteration, which is the repetition of consonant sounds at the beginning of words. It's important to differentiate consonance from alliteration and assonance, which is the repetition of vowel sounds within close proximity.
To identify consonance within "Opportunity" or any other given text, look for instances where consonant sounds are repeated at the end of adjacent or closely connected words.
