（2019 . 河南新乡一中高二检测）Scientists in Britain have managed t teach bumblebees（大黄蜂）t pull strings t get t fd and then pass n what they have learned t thers in their clny（群体）—shwing a high level f intelligence despite their tiny brains.
Researchers at Queen Mary University f Lndn said the experiments, ften used t test the intelligence f apes(猿) and birds, shwed fr the first time that sme insects are up t the task, and can als pass skills n thrugh several generatins.

Frm anther grup f bees given the chance t slve the task withut any training nly tw f 110 were successful.
Anther grup f bees was then allwed t bserve the trained bees pulling the strings, and 60 percent f them successfully learned the skill. Finally, trained bees were put in clnies, and the scientists fund the technique spread success fully t a majrity f the clny’s wrker bees.

Plants are bring.They just sit there phtsynthesizing（光合作用）while animals have all the fun.Right? Nt s much. A new study has fund that there is a lng histry f interactins between ants and plants. The ants and plants c-evlutin（协同进化）started with ants feeding n plants and plants evlving ant-friendly features.
Plants make a number f different structures that are specific fr ant use. Sme plants have evlved features that persuade ants int defending them frm attack frm ther insects and even mammals. These include hllw thrns that ants will live inside, r extra nectar(琼浆) n leaves r stems fr the ants t eat. Sme ants will just cheat and take the nectar and run, but sme will stick arund and attack anything that tries t hurt the plant. Other plants get ants t help the em mve their seeds arund, by prviding them with rich fd packets attached t the seeds. The ant will pick up the seed and carry it away, eat the fd packet, and leave the seed--ften in a nutrient-rich area where it ll grw better, and since it's farther away frm its parent, it wn t have t cmpete fr resurces.
But scientists weren’t sure hw the evlutinary relatinship between ants and plants gt started. If evlutin is an arms race between species develping ways t make use f their neighbrs, then scientists wanted t knw whether plants r ants fired the first sht. It was a chicken-and-egg questin whether things started with ants develping behavirs t take advantage f plants, r plants evlving structures t take advantage f ants.
The histry f ants and plants evlving tgether ges back t the time f the dinsaurs, and it's nt easy t tell frm fssils wh fired the first sht. Hwever, it is a questin f little significance. Scientists say their study matters because it prvides a lk at hw these widespread and cmplex interactins evlved.

B. make a fl f ants
C. prvide nutritin fr the seeds
