Context: We 'd find out later just why the first few hours were so quiet ! Orton soon came into view and we picked our way through several fields towards the village . We 'd been enjoying pretty good ground up to this point , but the last few hundred metres into Orton were a big muddy mess ! We eventually made it through the very boggy field well churned up by cattle , only to be faced with a sea of nettles on the other side of the gate !

Question: Why may be the reason we are not looking forward to going through the sea of nettles ?
Options:
0. Because we will need to carry the nettles all the way to Orton .
1. Because they are a big , muddy mess and hard to maneuver in .
2. Because the cattle droppings are all through the nettles .
3. They may sting and irritate our skin as our bodies touch them .
Answer: 3
