Which word would be correct in the sentence?

_______ should never be performed by a healthcare professional.

Stop

In the given sentence, "cease" means that the rain will come to an end or stop. It suggests that the rain will no longer be falling after sundown. Therefore, option D, "Stop," is the correct answer.

The sentence suggests that the new mother prefers to use cloth diapers instead of disposables. The word "cloth" is the appropriate choice, as it specifically refers to a material that can be used for making diapers. The options "close," "clothes," and "clothing" do not fit the context of the sentence and do not convey the intended meaning.

Influence.

In this context, "affect" means that the bad weather might have an impact or influence on the sales of the store owners. It suggests that the owners were concerned that the unfavorable weather conditions could potentially result in lower sales or other effects on their business. Therefore, option A, "Influence," is the correct answer.

The sentence suggests that the plumber used a tube to open up the blocked pipe, indicating that the tube needs to be able to navigate through the pipe's twists and turns. In this context, a flexible tube would be the appropriate choice, as it can bend and maneuver within the pipe. The options "rigid," "solid," and "perforated" do not convey the same idea of flexibility and adaptability as "flexible" does in this context.
