Question

Fill in the blank with appropriate preposition.

The scientist looked ____ the microscope. (through/in)​

Answer 1

The scientist looked through the microscope.

In this sentence, the appropriate preposition to fill in the blank is "through." The preposition "through" indicates that the scientist is looking into or examining the object, which in this case is the microscope.

To understand why "through" is the correct preposition, let's look at the meanings of the prepositions "through" and "in."

The preposition "through" is used to indicate movement or direction from one side or point to another, often indicating passage or entry. In the context of the sentence, the scientist is actively looking into the microscope, examining the object placed on the stage or slide.

On the other hand, the preposition "in" indicates location or position inside something. If we were to use "in" instead of "through" in the sentence, it would imply that the scientist is physically inside the microscope, which is not possible.

To summarize, the correct preposition to fill in the blank is "through" because it conveys the meaning that the scientist is looking into the microscope to observe or examine something.

Answer 2

`\textsf{The scientist looked\underline{ through } the microscope.}`

Step-by-step explanation:

We use the preposition through to refer to the act of seeing something from one side to the other.

We use the preposition in to refer to the act of being inside something.

In the sentence "The scientist looked through the microscope," the scientist is looking from one side of the microscope to the other, so we use the preposition through.

So, the sentence is "The scientist looked through the microscope".
