Answer

Brief Explanations:

The power of a lens is inversely proportional to its focal length ($P=\frac{1}{f}$, where $P$ is power and $f$ is focal length). When the focal length $f$ decreases, the power $P$ increases, and a lens with higher power is a stronger lens. A convex lens can produce both real and virtual images depending on the object - distance, and changing the focal length doesn't limit it to only real or only virtual images.

Answer:

It would make the lens stronger.
