We have no yet heard the weather … .

Analyze the question: The sentence is "We have not yet heard the weather __." We need a word that forms the correct collocation with "weather."

Explain the concept: In English, some words go together naturally (collocations). The standard expression for a report predicting the weather is weather forecast. Although "prediction," "broadcast," and "announcement" are related in meaning, they are not the natural partners of "weather" in standard usage.

Step-by-step solution:

• A. forecast: "weather forecast" is the standard, fixed expression. It means a report predicting upcoming weather. It fits perfectly: "We have not yet heard the weather forecast."
• B. broadcast: "weather broadcast" is possible, but it refers to the transmission itself and is less natural. "Heard the weather broadcast" is not the idiomatic choice.
• C. prediction: "weather prediction" exists, but it is typically used for the science or act of predicting, not for the report people listen to on radio or TV.
• D. announcement: "weather announcement" is not a standard collocation.

Tip: In English exams, always check for fixed collocations. Some common ones include weather forecast, news bulletin, heavy rain, and make a decision. If a phrase sounds like something you hear daily on NTA or Channels TV, such as "weather forecast," it is likely the correct one.

Also, a small note: the question says "We have no yet heard," which is a typo for "not yet." In the actual exam it should read "We have not yet heard."
