Juan likes to take a different route from his house to school every day of the week. Sometimes he follows the sidewalks all the way to school. Sometimes he takes a shortcut through the park. Sometimes he zigzags, looking at interesting plants and bugs as he walks. What is always the same about Juan's route to school?

The one thing about Juan's route to school that is always the same is his walk.

Explanation:

Juan takes different routes when going to school. Sometimes, he would walk along the sidewalk, at times take a shortcut through the park, zigzagging along the way and observing the plants and bugs along the way. These paths may differ for Juan as he makes his way to school.

But the thing that is always the same about his route to school is his walk. There is no mention of Juan ever riding a school bus or being taken to school by any vehicle for that matter.

Thus, his walk is always the same about his route to school.

the difference between an explicit and implicit meaning is that the explicit meaning of a poem is that the detail is exactly defined. nothing is left to interpretation. an implicit meaning is an implied meaning. kabir's poetry is both explicit and implicit in that it can be interpreted on different levels. the explicit meaning leaves nothing to interpretation while the implicit meaning leaves lots open to interpretation. an example of this is found in the poem "rumi and the spiritual lover". 

- "the basic difference between keywords and subjects is that subjects (or "subject headings") have been predetermined, while keywords have not. a keyword is an easy place to start because you can use any word that seems to fit your search; this is called "natural language" searching."
