College Board, SAT, and the acorn logo are registered trademarks of College Board.  \nReading and Writing  \nModule 1  \n(33 questions)  \nQUESTION 1  \nChoice A is the best answer because it most logically completes the text’s discussion of a prediction about a kilonova. In this context, a “theory” is an explanation that is considered scientifically acceptable. The text states that astronomers predicted in the 1990s that a collision between a black hole and a neutron star or between two neutron stars could release a massive gamma ray burst called a kilonova, explaining that they determined this possibility based on their extensive work with existing data and simulations (“calculations and models”) . In other words, the prediction was a theory—a well-supported explanation—that, as the text indicates, was later confirmed with observations in 2017.  \nChoice B is incorrect because the text indicates that it is the prediction made by astronomers in the 1990s that was confirmed in 2017, and a prediction of an event isn’t “evidence,” or proof, of that event’s existence, even when the prediction is based on extensive study. Further, there would be no need for later confirmation of something that was already recognized as evidence. Choice C is incorrect because in this context, a “constant” is a situation or factor that doesn’t change. The text indicates that it is the prediction made by astronomers in the 1990s that was confirmed in 2017, and there is no reason to describe the prediction as a constant because the text doesn’t suggest that the prediction was completely unchanged over time—it addresses only the making of the prediction and its later confirmation. Choice D is incorrect because the text indicates that it is the prediction made by astronomers in the 1990s that was confirmed in 2017; although a prediction might be informed by an “experiment,” or a controlled test, a prediction is an idea rather than a test.  \n2 SAT PRACTICE TEST \\#7 ANSWER EXPLANATIONS  \nQUESTION 2  \nChoice D is the best answer because as used in the text,“clear” most nearly means transparent, or see-through. Muir states that the water beneath the boat“was so clear that it was almost invisible,” suggesting that those on the boat were able to see through the water and easily observe plants and fish below the surface.  \nChoice A is incorrect. In some contexts “clear” can mean “simple,” or  \nuncomplicated, but Muir is describing the water, and water isn’t typically  \ndescribed as either simple or complicated. Muir emphasizes the water’s transparency, not its simplicity. Choice B is incorrect. In some contexts “clear” can mean “understandable,” or reasonable or easily comprehended, but Muir is describing the water, and it doesn’t make much sense to describe water as understandable. Muir emphasizes the water’s transparency, not how easily the water can be understood. Choice C is incorrect. Although “clear” can mean“obvious,” or easily seen or understood, in some contexts, Muir’s description emphasizes that the water “was almost invisible” and that the boat seemed to be“sustained in the air,” suggesting that the water was almost impossible to see, not that it was obvious.  \nQUESTION 3  \nChoice B is the best answer because it most logically completes the text’s discussion of how Maggie Lena Walker addressed the lack of financial services available to Black residents in Richmond, Virginia, at the turn of the twentieth century. In this context,“rectify” means to correct or remedy something undesirable. The text indicates that by chartering the St. Luke Penny Savings Bank in 1903, Walker took action to provide local Black residents with greater access to financial services like home loans and savings opportunities. This context supports the idea that she aimed to rectify the undesirable situation affecting ","cbCaiccAw37Rfc4U","https://ap.wps.com/l/cbCaiccAw37Rfc4U","pdf",1359981,46,"English","# Reading and Writing\n## Module 1\n## Question 1\n## Question 2\n## Question 3\n## Question 4","[{\"question\":\"What do the answer explanations provide for each question?\",\"answer\":\"They explain why the selected option is correct and why other choices do not fit the passage’s meaning or claims.\"},{\"question\":\"How are vocabulary words handled in these explanations?\",\"answer\":\"Key words are defined using the context of the passage, so meanings match how the author uses the term.\"},{\"question\":\"What kind of reasoning is used to justify answer choices?\",\"answer\":\"Each answer is tied to the passage’s specific statements, including logical relationships between predictions, evidence, and conclusions in real-world settings.\"}]","SAT Practice Test - 7 - Answer Explanations | PDF",116]
