Explanation for Question 29 From the Reading Section on the Official Sat Practice Test 4

Question 29 says which of the following does the author suggest about the female 2 goats mentioned in line 59. So let's look back in the passage for some 3 context here, about what they're talking about. If we read some of these sentences 4 around line 59, it says the company scientists took the gene for human antithrombin 5 and injected it directly into fertilized goat eggs. 6 Then they implanted the eggs in the wounds of female goats when the kids 7 were born. So baby goats are called kids. So when the kids were born, 8 some of them proved to be transgenic, the human gene nestled safely in their 9 cells. So let's see which answer choice goes along with the information presented here. 10 So answer choice a says they secreted antithrombin in their milk after giving birth. 11 So answer choice a is going to be incorrect because of these last few 12 words after giving birth. 13 So they're secreting antithrombin in their milk when they're just producing 14 milk regularly, not after giving birth. 15 So that's my answer. Choice a would be incorrect here. 16 If we look at answer choice B, it says some of their kids. 17 So baby goats, some of their baby goats were not born with the antithrombin 18 gene. If we look back into the passage, 19 it says that when kids were born, 20 some of them proved to be transgenic. 21 So that would imply that not all of them proved to be transgenic and 22 not all of them had the human gene in their cells. 23 So that could point to answer choice B being...
