    Social media and online platforms collect data all the time, but they use it to make
                     your experience better. For example, they show you content that matches your

                     interests and suggest products you might like. These platforms use this information
                     to improve the recommendations they give you, making it easier to find things you
                     enjoy.

                                  One afternoon, Sam and his sister Emma noticed something new in the garden. It
                               looked neat and watered, even though it hadn’t rained. How is the garden so green?
                         Sam asked.

                      Emma pointed to a small device. That’s a smart sensor! It tracks how much water the plants
                      need.

                      The sensor checks the soil’s moisture and sends the data to Dad’s phone. If the soil is too dry,
                      it tells him to water the plants. Dad smiled, holding his phone. The sensor just told me it’s time
                      to water the garden!

                      Sam smiled. The garden is smart!
                      Based on the above case, answer the following questions:

                      1.  How does the smart sensor help take care of the garden?

                      2.  What happens when the sensor detects that the soil is too dry?
