Understanding the Correct Preposition
In the sentence "The medicine only ______ infected tissue," the correct answer is "acts on." This choice is grounded in the specific meaning and usage of the phrase.
Meaning of "Acts on"
- Definition: The phrase "acts on" means to take action directed towards something. In this context, it indicates that the medicine is having a direct effect or influence on the infected tissue.
- Usage: In scientific and medical contexts, "acts on" is commonly used to describe how a drug or treatment interacts with a particular part of the body or a specific condition.
Why Other Options are Incorrect
- Acts out: This phrase typically means to express feelings or emotions through actions, often in an inappropriate way. It is not suitable in a medical context.
- Acts up: This term usually refers to something (like a machine or person) misbehaving or malfunctioning. It does not convey the intended meaning of a medicine working on tissue.
- Acts upon: While this could be seen as a valid option, it is less commonly used in medical contexts compared to "acts on." "Acts upon" might sound more formal or old-fashioned.
Conclusion
Choosing the correct preposition is essential for clarity in communication. In this case, "acts on" correctly conveys the action of the medicine in relation to the infected tissue, making it the best choice for the sentence.

The correct preposition to fill in the blank is "on."
Explanation:
- The verb "act" is often followed by the preposition "on" when referring to the effect or impact of something on a specific object or target.
- In this case, the medicine is acting on the infected tissue, indicating that it is having a direct effect on that particular area.
- Here, "on" signifies the location or target of the medicine's action.
- The prepositions "out," "up," and "upon" do not convey the intended meaning in this context and are therefore incorrect choices.
