a. I can see Matt and his family standing in the center of the image. On Matt's right, I believe is his grandfather and on his left, his mother. Standing on her left are her kids and her husband. And at the very left end of the family is the grandmother.
b. In the top left corner we can see the grandfather trimming the hedge and close to him, in the front of the picture his wife planting flowers. In the backround, Matt's father is cooking food on the barbecue and near to him, Matt's mother is sunbathing. In the bottom right corner, Matt is listening to music and next to him, his sisters are playing with toys.
