Final answer:
Yes, the government can keep watch over websites on the internet to protect children from potentially harmful material by using the enumerated power of regulating interstate commerce.
Step-by-step explanation:
Yes, the government can keep watch over websites on the internet to protect children from potentially harmful material. The authority to do so can be derived from the enumerated power of regulating interstate commerce. The government can argue that harmful content on websites can impact the well-being of children and therefore falls under the purview of regulating interstate commerce.
For example, the government can pass legislation that requires internet service providers (ISPs) to block or filter certain websites containing explicit or violent content. This can be done to ensure that children are not exposed to such material.
