This informational reference usually provides information covering one calendar year.
a. atlas
c. encyclopedia
b. dictionary
d. none of these

The answer is D: none of these.

The correct answer would be: an almanac. This is a record or catalogue which comprehends all days of a calendar year and which provides information usually related to astronomical data and other kinds of information related to political or religious affairs, although, contemporarily (for they have been around for centuries) an almanac can also include information related to sports or other forms of entertainment.  

i think the answer is either c or d

im thinking d might make more sense though

sorry if im wrong

the difference of the poems of walt whitman and emily dickinson is that whitman uses personification, whereas dickinson avoids figurative language. whitman incorporates transcendentalism and realism in his works. on the other hand, dickinson's poems talks about death and immortality.
