Student asked: Given the sentence "A man on scaffolding working on the masonry of a wall." can we conclude that "A man is laying new bricks on the wall."?
Options:
- yes
- it is not possible to tell
- no
Teacher's response: Let's think. Working on the masonry of a wall does not mean laying new bricks. It could mean filling in broken mortar or smoothing the mortar now that it has set to get rid of the spikey bits sticking out. It could be getting rid of mold or plants that have dug their way through the mortar and into the brick. I have seen that before. The answer is it is not possible to tell.
