What you can learn about a word from its etymology is:
B. word form history
C. root word
D. word components
Explanation:
Etymology is the study of the origin and meanings of a word, as well as of how it has changed over time. Therefore, from etymology, we can learn the original word, or root word, that generated other words we use nowadays. It also shows what components are part of that word. Even though etymology often tells us the time period in which a form of that words was employed, it does not state its year of origin. Therefore, we can eliminate letter A. Options B, C and D are all correct.
A direct object is the one receiving the action of the verb. In the sentence, the 'friends and family' were the one being asked by the 'we' so I think that's the answer.
