Answer 1

Correct statements:
- Vectors have a size and a direction.
- Vectors are indicated with arrows.
- Vectors can have positive or negative values.

Notes: "Size only" describes a scalar, not a vector. A vector's magnitude (size) is nonnegative, but its components or direction can be positive or negative.
