14. FALSE Local gulls, same way P2, L 1-7 An arctic tern, on its 20,000 km flight from the extreme south of South America to the Arctic circle will take no notice of a nice smelly herring offered from a bird- watcher’s boat along the way. While local gulls will dive voraciously for such handouts, the tern flies on.

  • While= Connective word to show contradiction

meaning that local gulls and migrating arctic terns behave in different ways when offered food.

15. TRUE definitions of migration, vary P3, L 1-3 But  migration  is  a  complex  issue,  and  biologists  define  it differently, depending on what sorts of animals they study.

  • experts=biologists
  • differently= Vary
16. NOT GIVEN few, agree, movement of aphids P4, L 5-10 So can the movement of aphids, when, ……….to where it started.

Nothing mentioned about the agreement by few or many.

17. TRUE Aphids’ journeys, affected, light P5, L 5-10 They  allow  for  the  fact  that,  for  example,  aphids  will  become sensitive to blue light (from the sky) when it’s time for takeoff on their big journey, and sensitive to yellow light (reflected from tender young leaves) when it’s appropriate to land.

  • They= aphids
  • become sensitive= affected
18. FALSE Dingle, migratory behaviors P5 L14 Dingel argues, is that it focuses,,,,,,, how evolution has produced them all.

His aim was not to distinguish between behaviors but above given.

19. G Dingle, migratory routes P1, L 8- 13

The   biologist   Hugh   Dingle   has   identified   five characteristics  that  apply,  in  varying  degrees  and  combinations,  to  all  migrations.  They  are  prolonged movements that carry animals outside familiar habitats; they tend to be linear, not zigzaggy.

  • Linear= straight line.
20. C prepare P1, L 13-17 they  (migrations)  involve  special  behaviour  concerning preparation (such as overfeeding) and arrival.” This means that to prepare for migration, animals eat more than they need for immediate purposes.

  • eat more than they need=overfeed
21. A during migration, unlikely  P1, L 17-22 And one more: migrating animals maintain an  intense  attractiveness  to  the  greater  mission,  which  keeps  them  undistracted  by  temptations  and undeterred  by  challenges  that  would  turn  animals  aside.”  This  means  that  during migration,  animals  are

unlikely to be discouraged by difficulties.

  • difficulties=challenges
22. E Arctic terns, ability P2, L1 An arctic tern, on its 20,000 km flight from the extreme south of South  America  to  the  Arctic  circle  will  take  no  notice  of  a  nice  smelly  herring  offered  from  a  bird- watcher‟s boat  along the way. While local  gulls will dive voraciously for such handouts, the tern flies on.

The arctic tern resists distraction because it is driven at the moment by an instinctive sense of something we humans find admirable: larger purpose.” This means that arctic terns illustrate migrating animals‟ ability to ignore distractions.

  • ignore=resist
23. speed pronghorns, eyesight, avoid predators P6, L23-26 Pronghorn,  dependent  on  distance  vision  and  speed  to  keep safe from predators.”

  • rely on=be dependent on

  • avoid=keep safe from
24. plains winter home, danger, snow P6,L 19-23 If  they  (pronghorns)  can’t  pass  through  again  in  autumn, escaping south onto those windblown plains, they are likely to die trying to overwinter in the deep snow.

  • danger= likely to die
25. bottlenecks route, contains three P6, L 13-16 These  pronghorns  are  notable  for  the  in-variance  of  their migration route and the severity of its constriction at three bottlenecks.
26. corridor/passageway construction, homes, narrow  P6, Last Sentence At  one of the bottlenecks, forested hills rise to form a V, leaving a corridor of open ground only about 150 metres wide, filled with private homes.

  • narrow= only about 150 metres wide
