It's been awhile! So, I'm working on this new project where I've formed a team to help me create GRE practice tests from scratch. Here is one of the tougher practice questions we came up with. Let me know what you think :D
The 19th-century poet Hanz Joerin always carried a litany of journals not because he was a(n) (i) writer but a(n) (ii) one: when inspiration did strike, his penmanship carried such preponderance that ink would bleed through to subsequent pages, rendering them unusable.
Blank (i)
A) concise
B) opportunistic
C) industrious
Blank (ii)
D) sporadic
E) vigorous
F) expressive

C and E (industrious and vigorous )

Explanation:

To be an industrious individuals means to be a hardworking, dedicated and diligent individual with a tireless and energetic attitude.

Vigorous personality means to be full of energetic and enthusiastic attitude. These were the best right choice of answer owing to the clue gotten from the subsequent phrase "his penmanship carried such preponderance" which shows poet Hanz Joerin was energetic enthusiastic and vigorous in writing. This is also implied by the statement "ink would bleed through to subsequent pages",
