1. The Professor thought there was light in the cave because of the presence of luminous gases.
To complete the sentence, we need to carefully read the given extract and look for any clues that could explain why the Professor thought there was light in the cave. Based on the image provided, it seems like the cave is dark and there are no apparent sources of light. However, the Professor believes that there is light because of the presence of luminous gases. This can be inferred from the fact that he specifically mentions the possibility of "phosphorescent gases."
2. While walking on the beach, Axel found shells and fossils.
To complete the sentence, we can infer what Axel found while walking on the beach by analyzing the given image. The image shows a person holding a shell and there are other shells scattered around as well. Additionally, there seems to be a fossil embedded in the rock on the bottom left. Therefore, it can be concluded that while walking on the beach, Axel found shells and fossils.
3. Hans threw his pickaxe into the water to see if it was magnetic.
To complete the sentence, we need to consider why Hans threw his pickaxe into the water. From the given extract and image, we can see that Hans mentions that the pickaxe is made of iron. Additionally, the image shows the pickaxe sticking to the magnetic field lines generated by the rock formation. Therefore, Hans threw his pickaxe into the water to see if it was magnetic.
4. Hans said the marks on his pickaxe were made by traces of iron.
To complete the sentence, we need to identify what Hans believes caused the marks on his pickaxe. Hans specifically mentions that the marks are made by "traces of iron." This can be inferred from the fact that he states, "Look, on my pickaxe there are long stripes, which must have come there in some other way than through friction." The image does not provide any direct evidence for this question, but based on Hans' statement, we can conclude that he believes the marks on his pickaxe were made by traces of iron.
