Question

Choose the word that best fits the sentence:

"After flipping the switch, the machine ______ smoothly and began its operation without any issues."

Accepted Answer

**Solution:**

1. The sentence describes a machine starting to work smoothly after a switch is flipped.

2. Let's analyze each option:

- **weltered**: Means to move in a disorderly or uncontrolled way. This does not fit the context of a machine starting smoothly.

- **invoked**: Means to call upon something such as a law or authority. This is unrelated to starting a machine.

- **activated**: Means to cause a device or system to start functioning. This perfectly fits the context of the machine beginning to operate.

- **captivated**: Means to attract or hold attention. This is irrelevant when describing a machine's operation.

3. Since the sentence is about the machine starting to work smoothly, **activated** is the most appropriate choice.

**Answer:** activated
