To find out, Engelmann observed the interactions of 15 chimpanzees over a 5-month period. Based on friendly interactions among chimp pairs, including eating together, the researchers found out each chimpanzee's closest “friend” and a “non-friend”. The researchers then asked the chimps to play a game, both with their friend and with their non-friend. In the game,chimps had a choice between pulling a “no-trust rope”. and a “trust rope”. When the no-trust rope was pulled, the first chimp immediately got a food he or she didn't like especially well. When the trust rope was pulled instead, the other chimp immediately got a much more attractive food and could choose to send a treat back to the first chimp(or not). In other words,the trust rope offered a win-win, but only if chimp one trusted chimp two enough to send something back. Each chimp played the game 12 times with his or her friend and another 12 times with his or her non-friend.
The findings suggest that human friendship isn't unique. "Human friendships don't rexesent an unusual thing in the animal world." Engelmann says, “Other animals, such as chipanzees, formn close and long-term bonds with selected individuals and trust friends in waly situations
sn. What does the underlined word "cronies" in the first paragraph most probably mean
A.Families. B.Friends.
C.Spocies D.Babios,
s What discovery have earlier studies made about chimpanzees
A. There exist friendships among them.

(2)当S1、S3断开，S2闭合时，则L1、L2两端的电压为2.5V、5V
(3)当S1、S3闭合，S2断开时，则通过L1、L2的电流为0.5A、0.3A
【详解】（1）当S2、S3闭合，S1断开时，灯泡L1短路，电路中只有L2，电压表示数为7.5V，即电源电压为7.5V
（2）当S1、S3断开，S2闭合时，两灯泡串联，电压表测L2的电压，此时电压表示数为5V，则灯L2两端的电压U2=5V，根据串联电路电压的规律，则L1两端的电压为
（3）当S1、S3闭合，S2断开时，两灯泡并联，电流表A测总电流，电流表A1测通过L1的电流；则通过灯L1的电流I1=0.5A，根据并联电路电流的规律可得，通过L2的电流
28．如图的电路中，电源由三节新干电池串联组成。开关S、S2闭合，S1断开时，滑动变阻器R2的滑片P移到最左端，电压表的示数为3V。开关S、S1闭合，S2断开时，滑动变阻器R2的滑片P移到最右端，电流表的示数为0.3A，此时通过灯泡的电流是0.2A。求：
（1）电源电压；
