Final answer:
The correct choice to fill the gaps is option b) upon, every, we, making the sentence: Today, all of us do, by our presence here, confer upon and hope to a newborn. Out of the experience of every human disaster that lasted too long, must be born a society of which all we will be proud.
Step-by-step explanation:
Reflecting on the context and the sentence structure, the most fitting words are option b) upon, every, we. Therefore, the sentence becomes:
Today, all of us do, by our presence here, confer upon and hope for the newborn (6). Out of the experience of every human disaster that lasted too long, must be born a society of which all we will be proud.
The pronoun 'we' refers to the collective society or community that will be proud of the society born out of disasters. 'Every' reinforces the magnitude of the disaster across all of humanity and 'upon' is a correct preposition to use after 'confer'.
