Let's analyze each sentence for grammatical errors and clarity. I will identify the errors and suggest corrections.**23. The underwater surfaces of sailboats, such as the centerboard and keel, are similar in cross-section and operate on the same principles as airfoils.*** **Error:** "tuch" should be "such". The comma after "sailboats" is correctly placed.* **Correction:** The underwater surfaces of sailboats, such as the centerboard and keel, are similar in cross-section and operate on the same principles as airfoils.**24. Modern systems of adoption, arising in the 20th century, tend to be governed mostly by comprehensive statutes and regulations.*** **Error:** "govern" should be "governed".* **Correction:** Modern systems of adoption, arising in the 20th century, tend to be governed mostly by comprehensive statutes and regulations.**25. Windmills were applied in regions where there was too little water, where rivers freeze in winter, and in flat lands where the flow of the river was too slow to provide the required power.*** **Error:** "too few water" is incorrect. The sentence also needs better structure for clarity.* **Correction:** Windmills were applied in regions with insufficient water, where rivers freeze in winter, and in flat lands where the river flow was too slow to provide the required power.**26. The forming of supercontinents and their breaking up appear to have been cyclical through Earth's history.*** **Error:** "being" should be "been". This is a past participle needed to complete the perfect tense.* **Correction:** The forming of supercontinents and their breaking up appear to have been cyclical through Earth's history.**27. A pharaoh would have to have significant power to convince his subjects that it was worthwhile sacrificing their lives on earth for the pharaoh and his comfort in the next life.*** **Error:** "live" should be "lives". The phrasing "worth sacrificing their live" is awkward. "Worthwhile" is a better word choice than "worth".* **Correction:** A pharaoh would have to have significant power to convince his subjects that it was worthwhile sacrificing their lives on earth for the pharaoh and his comfort in the next life.**Regarding sentence 22:** The provided text ("72 Wanth is chithonic figure in thom it is variety of lism of funerary art, such as in tomb paintings and") is grammatically incorrect and unclear. It needs significant revision to be understandable. More context is needed to understand the intended meaning. It seems to be attempting to describe a figure ("Wanth") related to funerary art, but the wording is nonsensical.
