Explanation for Question 48 From the Reading Section on the 2021 May Sat (International)
Hey guys. So question 48 says according to the passage, 2 what is the relationship between the Spanish and the California populations of yellow star 3 thistles? So, um, 4 it seems to be that based on what it tells us here, 5 uh, at the ending that these are 6 here, let me find it. And pollen answered 68, 7 um, comes around here. 8 He says, this suggested the California plans. 9 Uh, the, the yellow star thistles are probably not yet fully fledged species, 10 but are well on their way towards it mere 86 to 350 years after 11 they separated from their Spanish ancestors. If they continue to diverge at the same, 12 right? They might well be quite distinct human grade species within a few more 13 centuries. So it's telling us that based on their ancestors, 14 they're changing quite rapidly. They're still the same species right now, 15 but eventually they may not be. So, 16 um, it seems to me that it's not a, they're not recognized as differently, 17 different, but closely related species. 18 They're still the same species option. B says they're currently the same species, 19 but appear to be diverging into distincts into distinct species. 20 This is exactly what saying they're still the same species right now, 21 but they're getting further apart. And over the years, they're going to get further 22 and further apart, very likely C says the California population has a hybrid offspring. 23 Um, um, 24 it's not, uh, the Spanish, he also has this all ends native to California. 25 That's...
