Can anyone help me with this static electricity lab?

I have done the experiment but am really confused about these questions.

1. Describe and explain what happens as the two T-strips are brought closer together.
2. Can you tell from your experiment so far whether the T-strips carry a positive charge or a negative charge? Briefly explain your answer.
3. Using the additional equipment that has been supplied to you (the PVC pipe, glass rod, wool cloth, and rabbit fur) and the information in Table 1, design and carry out an experiment that allows you to determine the sign of the charge on the T-strips. Describe your experiment and its results.
