What does the author mean by the statement “bald eagles mate for life”?

The option that best describes what is meant by the author’s use of the statement “bald eagles mate for life” is: Two bald eagles are a couple until one passes away. The remainder of the sentence helps you to understand what is meant by “mate for life,” as it informs you that when one dies, the other one will not hesitate to find a new mate; therefore, you can determine that two bald eagles remain a couple until one passes away. The passage does imply that bald eagles use the same nest for a long period of time; however, the nest does not relate to an eagle’s mating habits in this passage.
