我们根据题目给出的位置回到原文：Forhundredsofmillionsofyears,turtles（海龟）havestruggledoutoftheseatolaytheireggsonsandybeaches,longbeforetherewerenaturedocumentariestocelebratethem,orGPSsatellitesandmarinebiologiststotrackthem,orvolunteerstohand-carrythehatchlings（幼龟）downtothewater'sedgelesttheybecomedisorientedbyheadlightsandcrawltowardsamotelparkinglotinstead.AformidablewallofbureaucracyhasbeenerectedtoprotecttheirprimenestingontheAtlanticcoastlines.Withallthatattentionpaidtothem,you'dthinkthesecreatureswouldatleasthavethegratitudenottogoextinct.

结论二：转折前后，逻辑表意相反，巧用转折，可正确推理语义题的言外之意！
综上所述，转折逻辑是我们在精确阅读中砍分的利器！因此，当文章中出现：but,however,while,yet,instead（of）,still,onthecontrary等表示转折逻辑的单词或短语时，请大家打起十二分精神，因为答案正在向你走来！
