By a table with several boxes and two coffee cups on it, a woman in a green sweater is opening a small box and another person (whose head cannot be seen) is operating a small handheld electronic device.
Members of congress opening care packages.
It is a woman and one other person not members of congress.  One of them is opening something while the other is operating something.
A singular woman opening a small box is not the same as multiple members of congress.
A person is one single, Members are several together
