Hi, in the following paragraph the phrase ‘which makes them intelligent’ certainly is meant to relate to the fact that the microprocessors make the panels intelligent. But couldn’t the subject also be the microprocessors themselves requiring the verb ‘make’ instead of ‘make’?
They contain heating elements to prevent snow and ice accumulation. The panels have microprocessors, which makes them intelligent. This allows the panels to communicate with each other, a central control station, and vehicles.
I don’t really think so. The format of these sentences is reason -> result. So the reason is the panels have microprocessors and the result is the panels are intelligent. I don’t see any way that the microprocessors being part of a panel would make the microprocessors smart, but I guess in a completely different context it could work.
