Complete the text by filling in the blank with the most logical and precise word.
Cevap:For decades, astronomers believed that the atmospheres of hot Jupiters—gas giant exoplanets that orbit very close to their parent stars—were relatively uniform in composition. However, recent spectral data obtained by the James Webb Space Telescope have 【challenged】 this assumption, revealing significant chemical variations between the day and night sides of these planets.
Cevap
challenged (or other synonyms indicating contestation or refutation, such as undermined or refuted)
The sentence begins with 'However', signaling a contrast with the traditional belief that hot Jupiters had uniform atmospheres. The new data revealed significant variations, which directly conflicts with this traditional belief. Therefore, the blank must be filled by a word meaning to contest, weaken, or prove false, such as 'challenged', 'undermined', or 'refuted'.
