TEXT: Choice A is correct. It's given that length WZ and length XY intersect at point Q. It follows that angle WQX and angle YQZ are vertical angles, which means they are congruent to each other. The figure shows that angle W and angle Y both have a measure of a°, so they are congruent to each other. Therefore, triangle QWX and triangle QYZ are similar triangles, where length WQ corresponds to length YQ and length WX corresponds to length YZ. Since the lengths of corresponding sides in similar triangles are proportional, it follows that YZ/YQ = WX/WQ. It's given that YQ=21, WQ=70, and WX=60. Substituting 21 for YQ, 70 for WQ, and 60 for WX in the equation YZ/YQ = WX/WQ yields YZ/21 = 60/70, or YZ/21 = 6/7. Multiplying each side of this equation by 21 yields YZ = 18 Therefore, the length of YZ is 18.
Choice A is correct. #SATPractice
![TEXT: Curious about how people visually perceive objects in their dreams, Stephen LaBerge and team recruited lucid dreamers-people aware that they're dreaming as it's happening-for a research study. These participants were reliably able to signal when they had entered a dream state; the team then observed participants' eye movements as they slept. [UNDERLINE START] The smoothness with which participants' eyes tracked objects in their dreams closely matched how sighted people who are awake visually track objects around them, [UNDERLINE END] suggesting to the team that the brain perceives dream objects as the product of something other than pure imagination.
Which choice best states the function of the underlined portion in the text as a whole?
A) To offer key evidence that undermines LaBerge and team's initial hypothesis
B) To show the unexpected result that led LaBerge and team to change the focus of their study
C) To illustrate an important real-world implication of LaBerge and team's main finding
D) To identify a comparable circumstance that helps justify LaBerge and team's conclusion](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:lcopwi3vteutjzdvsq4227i3/bafkreifz3agr2ioxvhaopc26vm5mheujpxfuuv3hp2n3bta2ee5ugjtwfa)

The following text is adapted from Pam Muñoz Ryan's 2020 novel Mañanaland. In the village where Max lives, there is an old fortress called La Reina. Children in the village say that the fortress is haunted.
For as long as he could remember, Max had begged Papá [his father] to take him to see La Reina and the ruins up close. He'd be a hero among his friends if he was the first boy to cross the haunted gates! Just because Papá didn't believe in ghosts didn't mean they weren't there. Maybe this summer Papá would finally take him. He was almost twelve.
