(Select the best word. Note: two words produce sentences alike in meaning — choose the most accurate.)

thrilled about✔️
confident in
keen on
eager for

Correct Answer Explanation

Scientists got far more than expected — data from Neptune was a wonderful surprise. Thrilled about captures the positive emotional reaction to an unexpected bonus. 'Elated by' is the synonym pair in the original. 'Confident in' and 'keen on' imply prior expectation. 'Eager for' describes anticipation before the fact, not a reaction after receiving unexpected data.
