13.Biometic access-control systems-those using fingerprints, voiceprints, etc, to regulate admittance to restricted aread-work by degrees of similarity, not by identity. After all, even the same finger will rearely leave exactly identical prints. Such systems can be adjusted to minimize refusals of access to legitimate access-seekers. Such adjistments, however, increase the likelihood of admitting impostors.

15. One cariety of partially biodegradable plastic beverage container is manufactured from small bits of plastic bound together by a degradable bonding agent such as cornstarch. Since only the bonding agent degrades, leaving the small bits of plastic, no less plastic refuse per container is produced when such containers are discarded than when comparable nonbiodegradable containers are discarded.

这两个题干花了我好长时间.还是有些模模糊糊.请大家帮忙翻译一下吧!尤其是有下划线的地方.谢谢谢谢!

Biometric access-control systems—those using fingerprints, voiceprints, etc., to regulate admittance to restricted areas—work by degrees of similarity, not by identity. (Biometric access-control systems 以相似程度，而不是相同工作）After all, even the same finger will rarely leave exactly identical prints.(毕竟，即使是相同的finger也很难完全相同） Such systems can be adjusted to minimize refusals of access to legitimate access-seekers. Such adjustments, however, increase the likelihood of admitting impostors.（这样的系统能被调整从而最小化的拒绝合法的进入者，however,同时增加了冒名顶替者进入的可能性）

Since only the bonding agent degrades, leaving the small bits of plastic, no less plastic refuse per container is produced when such containers are discarded than when comparable nonbiodegradable containers are discarded.
因为仅仅粘结剂降解，留下了小塑料片，每个container产生的塑料并不比（当同样不能降解的container 被discarded时）的少。
