Medium difficulty TC. Is this question ambiguous?

I am confused here.
August and approbation are also a correct pair for this question.
Having unlimited confidence in her own abilities can make her arrogant, but impressive at same time. Approbation also correctly goes with the same reasoning as she has high praise for others.

chatGPT is also saying same thing :joy:. I saw Gregā€™s explanation which was too short, and it did not address this ambiguity.

Please clarify. Thankyou!

Itā€™s not an ETS question, donā€™t worry about it too much.

Having ā€œunlimited confidenceā€ would not make you august, unlimited anything is often bad, right?

i think haughty and disdain is the answer
