A  flower's  colour,  however,  isn't  a  full-proof  guide  to  a  good  lunch.  That's  because  the  colour  can  change  depending  on  the  angle  at  which  sunlight  hits  its  petals.  A  yellow  flower,  for  example,  may  look  somewhat  blue  from  one  angle  and  red  from  another.  Scientists  call  this  kind  of  colour  change  iridescence.  'It's  the  same  that  makes  a  rainbow  appear  in  a  soap  bubble  or  on  a  CD,'  says  Beverley  Glover.  She  studies  plants  at  the  University  of  Cambridge  in  England.  In  2009,  Glover  and  her  colleagues  showed  that  even  when  petals  look  ,  bees  can  still  tell  which  flowers  likely  hold  food.  But  she  and  others  noticed  something  odd  about  iridescence.  It's  not  quite  as  flashy  in  plants  as  in  other  life  forms,  Glover  says.  The  backs  of  jewel,  beetles,  or  the  wings  of  certain  butterflies,  for  instance,  shine  and  shimmer  a  lot  more.  The  researchers  tested  their  hypothesis  in  the  lab.  They  trained  a  group  of  bees  to  associate  fake  purple  flowers  with  getting  more  nectar.  Then  the  team  tested  the  bees.  They  added  non-shimmery    flowers  with  purple-blue  and  purple-red  hues  to  the  bees'  flight  path.  The  bees  passed  the  test,  ignoring  flowers  that  weren't  perfectly  purple.  Second  group  of  bees  was  trained  to  drink  from  fully  flashy,  'perfectly  iridescent'  purple  flowers.  But  when  the  team  added  perfectly  iridescent  flowers  in  different  hues,  the  insects  checked  them  for  nectar,  too.  A  third  group  of  bees,  however,  had  no  problem  finding  the  right  flowers  when  the  petals  had  only  a  little  bit  of  bling.  These  bees  were  trained  to  drink  from  'iridescent'  purple  flowers.

Correct answer: shimmery

Explanation: The word 'shimmery' describes a quality of light that reflects off the petals, indicating a subtle iridescence. This fits grammatically as it is an adjective that modifies 'petals,' and contextually, it aligns with the discussion of how flowers can appear under different lighting conditions.

Meaning: 'Shimmery' refers to a soft, flickering light or sheen, often seen in iridescent surfaces.

Wrong options:

  • indigenous: 'Indigenous' is an adjective that refers to native species or populations, which does not relate to the visual quality of petals.
  • fake: 'Fake' implies something artificial or not real, which does not accurately describe the appearance of petals in this context.
  • phenomenon: 'Phenomenon' is a noun that refers to an observable event, which does not fit as a description of the petals.
  • chant: 'Chant' is a verb that means to sing or recite in a rhythmic manner, which is unrelated to the visual characteristics of flowers.
  • regular: 'Regular' is an adjective that suggests something standard or typical, which does not convey the unique quality of light reflection being discussed.
Correct answer: fake

Explanation: The term 'fake' is used to describe the artificial flowers that were part of the experiment. It fits grammatically as it is an adjective modifying 'flowers,' and contextually, it aligns with the idea of the bees being trained to associate these non-natural flowers with nectar.

Meaning: 'Fake' refers to something that is not genuine or real, in this case, artificial flowers.

Wrong options:

  • indigenous: 'Indigenous' refers to native species and does not apply to the context of artificial flowers.
  • imperfectly: 'Imperfectly' is an adverb that describes the manner of something being not perfect, which does not fit as a noun or adjective for flowers.
  • phenomenon: 'Phenomenon' is a noun that describes an observable event, which does not fit as a descriptor for flowers.
  • shimmery: 'Shimmery' is an adjective that describes a quality of light, which does not apply to the classification of the flowers as artificial.
  • chant: 'Chant' is a verb that does not relate to the description of flowers and is irrelevant in this context.
  • regular: 'Regular' suggests something typical or standard, which does not accurately describe the artificial nature of the flowers.
Correct answer: imperfectly

Explanation: The word 'imperfectly' serves as an adverb modifying 'iridescent,' indicating that the flowers do not exhibit full iridescence. This fits grammatically and contextually, as it describes the quality of the flowers that the bees were trained to recognize.

Meaning: 'Imperfectly' means not fully or completely, suggesting that the iridescence is present but not to a perfect degree.

Wrong options:

  • indigenous: 'Indigenous' refers to native species and does not relate to the quality of iridescence in flowers.
  • fake: 'Fake' describes something artificial, which does not fit as an adverb modifying 'iridescent.'
  • phenomenon: 'Phenomenon' is a noun that does not fit grammatically or contextually in this sentence.
  • shimmery: 'Shimmery' is an adjective that describes a quality of light, which does not fit as an adverb in this context.
  • chant: 'Chant' is a verb that does not relate to the description of iridescence and is irrelevant here.
  • regular: 'Regular' is an adjective that suggests something typical, which does not accurately describe the degree of iridescence being discussed.
