Question

for their part, pakistan officials have chafed at the conditions attached to u.s. foreign aid.
in this sentence, chafed means:

• gasped through a display of force
• felt extreme irritation or anger
• given testimony in a court of law
• experienced a feeling of well - being

Explanation:

"Chafed" in the context of Pakistan officials reacting to conditions on U.S. foreign aid implies strong negative emotion. "Felt extreme irritation or anger" fits this context as being frustrated with imposed conditions. The other options: "opposed through a display of force" is too violent - no indication of force; "given testimony in a court of law" is out of context (no court mentioned); "experienced a feeling of well - being" is positive (opposite of the situation).

Answer:

felt extreme irritation or anger
