Explanation:

First Question (Khufu's Boat):

Khufu's boat (the Solar Boat of Khufu) has dimensions of approximately 143 ft long and 19.5 ft wide. Wait, but in the options, the selected one was 130 ft long and 75 ft wide? Wait, no, correction: The actual Khufu's boat (discovered) is about 143 feet (43.6 meters) long and 19.5 feet (5.9 meters) wide. But among the given options, the correct one based on standard knowledge (maybe the question's context) – wait, the options: let's recheck. Wait, the options are: 450x75, 450x23, 130x75, 143x19.5. The correct historical data for Khufu's boat is ~143 ft long and 19.5 ft wide, so the option "143 ft long and 19.5 ft wide" is correct. But in the image, the selected one was 130x75? Maybe a typo, but based on knowledge, the correct answer is the option with 143 ft long and 19.5 ft wide. Wait, the user's image shows the selected radio button on "130 ft long and 75 ft wide" – but that's incorrect. Wait, no, maybe the question's options have a variation. Wait, perhaps the question is from a specific source. Alternatively, maybe I made a mistake. Wait, let's check: Khufu's boat (the one found near the Great Pyramid) is 143 feet (43.6 m) long and 19.5 feet (5.9 m) wide. So among the options, the correct one is "143 ft long and 19.5 ft wide".

The fossil record and sediment layers show that life evolved from simpler to more complex. Single - celled organisms (prokaryotes, then eukaryotes) appeared first, then plants (photosynthetic organisms), then reptiles (amniotes, after amphibians), and finally mammals (more complex vertebrates). So the order from earliest to latest is Single - celled organisms, Plants, Reptiles, Mammals.

Answer:

143 ft long and 19.5 ft wide (the fourth option: "143 ft long and 19.5 ft wide")
