Hi Elif, let's look at this English grammar question about verb forms and time relationships.
Analyzing Verb Structures
The sentence says, Galileo is known, followed by a gap, significant observations about celestial bodies. We need to find the correct form of the verb make to fill that gap.
The early scientist Galileo is known --- significant observations...
First, let's look at the phrase, is known. In English, when we use the passive construction, is known, it is typically followed by a to-infinitive.
This immediately helps us narrow down our options to A or C, as they both start with the word to.
A) to make
C) to have made
Now we need to decide between the simple infinitive, to make, and the perfect infinitive, to have made.
Simple vs. Perfect Infinitive
| Structure | Usage |
|---|---|
| To + Verb | Commonly used for present or future actions. |
| To + Have + Past Participle | Used for actions that happened in the past. |
