📖 Part 2: Cloze Passage - The Underground Adventure

Last week, our class went on an amazing field trip to explore different places that exist "below" or "under" ground level. First, we took the _____________ train that travels beneath the city streets. Our teacher, Mrs. Johnson, couldn't come with us, so we had a _____________ teacher named Mr. Brown.

At the marine centre, we learned about a special _____________ that can travel deep under the ocean. The guide explained how these vessels can _____________ completely underwater and explore the ocean floor. We watched a video showing how the submarine would slowly _____________ beneath the waves until it disappeared from sight.

Next, we visited a farm where we learned about soil layers. The farmer showed us the topsoil and then dug deeper to reveal the _____________ underneath. He explained how plant roots grow down into these lower layers of earth.

On our way home, we drove through a quiet _____________ located just outside the main city centre. Our bus driver had to _____________ our large group into two smaller groups because one bus wasn't big enough for everyone.

Finally, our maths teacher gave us a problem: if we started with 50 students and had to _____________ the 8 students who went home early, how many students completed the full trip?
