Official GRE verbal reasoning practice set 1 Q4 and Q7 (easy)

Hello, Could someone please help me with solving these using the math strategy. And if possible then some advice on how to solve the 3 blank questions. Thank you.

Q 4)

Blank(i) is about the rivals who were in their peak form but still lost and even complained privately to the judges, from these clues its look like they’re **very frustrated ** about their loss against the winning pair.

Also, we know that the rival are in their peak form and the second blank wants to describe this, thus, you can re-use peak form .

Hey, Thank you.
