DAY 59
1.CR
(1) C ❌, 正确: E
确实在“能否解决财务危机”这个result上, C不如E.
(2) B, ❌, 正确: A
Reasoning: method = size variance, asm, dh smaller, dh- uniformed
其实B只是间接地说明wild animal, 而A选项在具体说明 domestic horse 并不那么统一, 大小也不定, 反驳了专家的两个假设.
2. RC
- **Main Idea and structure:**
- a decrease in ocean temperature lead to a rise in ptpk - counterintuitive vs tradition - nutrient level
- temperature - ecosystem dynamic, cooling - prompt species - migration into SF Bay
- further impact - predator species increase - so clam decrease - so ptpk bloom
My: BBADA
An: BEADA
(2) contribute 不等于 help, 所以错选B. 只是在列举影响phytoplankton boom的影响因素
3.DI
My: BBCC

(3) A= 150/((800+600)/0.8)=7.5%
C= 100/((500+400)/0.75)=1/12=8.3%
D=200/((2000+1800)/0.95)=5%
E=180/((1000+900)/0.85)=8%
F=120/((700+550)/0.9)=10.6% ❇️
G=90/((450+350)/0.7)=0.8%
I=160/((900+800)/0.85)=0.7%
RC:B E A D A
P1: counterintuitive conclusion:
ocean temperature下降—》phytoplankton blooms
P2: cooling—》migration to SFB —》predator增加—》clam下降—》phytoplankton blooms
