This is useful for data encapsulation and maintaining state in asynchronous programming.

Flexbox, or the Flexible Box Layout, is a CSS layout model that allows items in a container to be arranged and aligned efficiently. It works by defining a container as a flex container using `display: flex;`, which enables its direct children (flex items) to be laid out along a main axis (horizontal or vertical). You can control the alignment, direction, spacing, and size of these items using properties like `flex-direction`, `justify-content`, `align-items`, and `flex-wrap`. This makes it easier to create responsive layouts without using floats or positioning.

3. **Literal**: A value that represents a specific piece of data, such as a string, number, or date.
4. **Subject**: The resource being described in a statement.
5. **Predicate**: The property or relationship of the subject, linking it to the object.
6. **Object**: The resource or literal that the subject is related to through the predicate.
7. **Triple**: The basic unit of RDF, consisting of a subject, predicate, and object.

Right Answer:
To combine an XML document with a signature so that the signature signs the original document, you can use the following steps:

1. Create the original XML document.
2. Generate a canonicalized version of the XML document.
3. Create a signature using a cryptographic algorithm (like RSA) on the canonicalized XML.
4. Wrap the signature in a `<Signature>` element according to the XML Signature specification (e.g., using the `<ds:Signature>` element).
5. Append the `<Signature>` element to the original XML document, ensuring it is placed in a way that maintains the integrity of the original content.

This results in an XML document that includes the original content and the signature, which verifies the authenticity of the original document.
