F They were experienced climbers and they (prepare)
carefully for
their trip. They knew there was a cave halfway
up the mountain.
g They spent a long time searching for the cave

dark entrance of the cave nearby.
h Luckily they (bring)
warm clothes and plenty of food with them,
and they waited safely in the cave.
