At the end of the … . the National Anthem is played on our radio station.

Analyze the question

The sentence is: "At the end of the ___, the National Anthem is played on our radio station." We need the word that describes the period when a radio station is broadcasting each day.

Explain the concept

Look at what each word means:

• Programming: the planning or scheduling of programmes, or writing computer code. It does not describe a period of broadcasting.
• Production: the making of a programme or goods. A station does not close its day with "the production".
• Transition: a change from one state to another. It does not fit radio broadcasting.
• Transmission: the sending out of radio or TV signals, meaning the broadcast itself. Stations speak of the "day's transmission", and they open and close transmission with the National Anthem.

Solve step by step

1. The sentence is about a radio station playing the anthem at the end of its broadcasting day.
2. The word needed must mean the broadcast period or signal sending.
3. Only "transmission" has this meaning.
4. "At the end of the transmission, the National Anthem is played on our radio station" is natural and correct.

Answer: D. transmission

Exam tip: For broadcasting vocabulary, link "transmit" with signals sent out through radio or TV. When a station "goes off air" for the day, that is the end of its transmission. In the Lagos-based phrase "closing transmission", you can remember it as the point when the anthem plays and the station signs off.
