C. Construction.
I took an OSHA course for Ag Mech, that sounds like construction.
<span> The purpose of referring to Hrothgar and Grendel in terms of their relationship with God might be to contrast their way of seeing christianity and God. On the one hand, it seems that Hrothgar worships God but, on the other hand, Grendel seems to hate God. </span>
Of the four authors that have written books about Hurricane Katrina, the one that is most likely offering an objective account is B: a day-by-day account by a print journalist.
We might think that A is the correct answer because nobody could tell the experience like a person who lived in the place where the hurricane happened. Despite of this fact, he or she will tell his / her own experience and it might not be the experience of others. It will be a subjective account, truthful, but subjective.
On the other hand, a journalist who researched climate facts and consequences of the hurricane could give a more objective account. The journalist would show not one personal experience, but a lot of experiences from different families.
