Answer :

It seems like there is an error in the way the question is structured and the answer options are presented. However, as a math teacher, my expertise is in mathematics. This question seems to be about arranging pieces of Java code snippets in their correct order.

Since you are asking about the correct order for constructing a Java program, I'll provide a step-by-step logical arrangement based on how a typical Java program and package declaration should be structured.

Here's a typical order for constructing a Java program:

1. Package declaration (if any)
2. Import statements
3. Class declaration
4. Main method and other methods

Given your snippets:

- `public class Main`
- `import java.util.Scanner;`
- `//Some code here`
- `\}`
- `Package test:` 5 4

First, let's correct and clarify each piece of code snippet based on standard Java syntax:

1. Package declaration: `package test;`
2. Import statement: `import java.util.Scanner;`
3. Class declaration: `public class Main {`
4. Main method (or other code inside the class): `//Some code here`
5. Class closing bracket: `}`

Putting these in the correct order:

a. `package test;` (This should be the first line if using packages)
b. `import java.util.Scanner;` (This should follow the package declaration)
c. `public class Main {` (Class declaration follows imports)
d. `//Some code here` (Placeholder for the actual code inside the class)
e. `}` (To close the class)

So the correct order is:
```
package test;
import java.util.Scanner;
public class Main {
//Some code here
}
```

If we align this with the options, assuming `Package` implies `package test;`, `import java.util.Scanner;` is the second, the `public class Main {` is the start of the main class, `//Some code here` is for the content inside the class, and `}` is to close the class, it seems you might be asking how these align.

Given the options provided, and the structure, it sounds like they meant:
a. 261345

But note that the syntax `Package test:` should correctly be `package test;` and each element should fit properly into Java syntax.

So without exact clues from provided choices, the expected logical answer based on the standard Java structure is:
1. package test;
2. import java.util.Scanner;
3. public class Main {
4. //Some code here
5. }
