Which word would be correct in the sentence?

_______ should never be performed by a healthcare professional.

Two-sided.

In medical terminology, "bilateral" refers to something that affects or is present on both sides. In the context of the sentence, it indicates that the weakness observed in the patient's ambulation is affecting both sides or both legs. The word "bilateral" is used to describe a condition or characteristic that is symmetrical or occurring on both sides of the body. Therefore, option A, "Two-sided," is the correct answer.

Alcohol.

The word "alcohol" refers to a colorless, volatile liquid compound that is used as a solvent, in antiseptics, and in beverages. It is the correct spelling for the substance mentioned in the sentence.

The term "ubiquitous" refers to something that is present or found everywhere, or that occurs or exists everywhere at the same time. It implies that something is pervasive, common, or widely encountered in various places or situations. The options "Iesha, Frazier," "finally reckoned," and "uncertainty" do not accurately represent the meaning of "ubiquitous."

To address a section of a fence that is falling apart, a homeowner would need to buttress it. "Buttress" means to reinforce or support something, often by adding additional structural support. In the context of the falling-apart fence, the homeowner would need to provide additional support or repair the section to prevent it from collapsing further. The options "flounder," "degrade," and "hinder" do not convey the appropriate action needed to address the situation with the fence.
