Q1 Honeybees A. have a rudimentary ability to convey information B. have clearly segregated roles C. are found in equal numbers of male and female D. often relocate to areas with certain types of flower |
1/ As a result, they maintain strict divisions of labour, based on sex, with all males functioning as drones to fertilize and care for the eggs, and all females, with the exception of the single fertile queen, responsible for fetching nectar for the colony’s progeny. 2/ In addition, honeybees have devised a sophisticated system of communication to relay important information from member to member. |

Q2 Research conducted in the 1970s A . was undertaken using traditional hives. B. determined that forager bees had special markings. C. closely studied the phenomenon of the honeybee body language. D. concluded that there was no discernible pattern to the movement of the bees. |
1/ This so-called honeybee dance was first interpreted by German zoologist Karl von Frisch in the early 1970s. 2/ To facilitate observation, von Frisch and his students built several glass walled hives and marked a collection of worker bees, or foragers, with paint. 3/ when the bees returned he carefully recorded their movements, the angle and direction of their flight, and any additional visual cues offered to the colony. 4/ What von Frisch discovered was that each aspect of the dance indicated certain details about the location of the nectar reserves and recruited others to return to the site. |

Q3 To identify that the source of nectar is close, forager bees A. will repeatedly fly the same direction B. will begin to move only when other bees are watching C. will run straight forward D. will repeat a pattern of flying in one direction then abruptly reversing direction |
1/ If it is less than 50 meters from the colony’s nest the bee will fly around in narrow circles, and then suddenly fly in the opposite direction. 2/ She will repeat this pattern, which von Frisch’s team called the round dance, until she has recruited several other workers to return with her to the field. 3/ When the distance is greater than 50 meters, but less than 150 meters, she will perform a sickle dance, a crescent shaped flight course. 4/ If the field is farther than 150 meters, the forager will act out a waggle dance in which she will run straight ahead briefly before returning to her original position in a semi-circular movement. |

Von Frisch focussed on a number of 4 clues to deduce how bees communicated.
The bee will move forward for 5 for every 1000 metres away the food source is.
To locate the direction of the nectar, the forager will base its movements on the position of 6
For food sources over 150 metres away, the forager will indicate distance with a 7 dance.
It has been argued that 8 as well as movement may help to locate food sources.

The bee will move forward for Q5______ for every 1000 metres away the food source is. |
The length of the forward run coincides with the distance of the food supplies; for example, a 2.5 second run indicates that the nectar was found about 2500 meters way. |
Note: “2.5 seconds” can be mistaken as the answer. However, as the distance in the question is 1000 metres, it only takes the bee 1 second to run forward. |

To locate the direction of the nectar, the forager will base its movements on the position of Q6_______ |
1/ Recruits also need to know the direction in which they should fly to arrive at the appropriate foraging location, and this information is communicated via the bee’s angular orientation to the hive. It, however, is not a direct connection to the position of the food supplies from the hive, but its location relative to the sun. 2/ Therefore if the food is situated directly opposite from the sun, the bee will fly a straight run vertically downward; if it is in the same direction as the sun, it will fly directly upward from the colony nest. A position 60 degrees to the right of the sun will prompt the bee to fly downwards at a 60 degrees angle toward the right of the nest. Moreover, because the sun is in constant motion throughout the day, the bee’s orientation will shift depending on the time at which the dance is performed. |

It has been argued that Q8_______ as well as movement may help to locate food sources. |
Sceptics of von Frisch’s findings, however, claim that visual cues are not enough to provide all the clues necessary to convey the location of a food resource. Several scientists, among them Adrian Wenner, believe that the dance is only one component of honeybee communications; odour is the second key element. |

11
The honeybee dance is only performed when the sun is visible.

Q9 Drone bees communicate using a complicated set of movements. |
As a result, they maintain strict divisions of labour, based on sex, with all males functioning as drones to fertilize and care for the eggs. |
Male honeybees act as drones to fertilize and take care of the eggs. As drones, honeybees do not work or move much. Thus, they WOULDN’T use a complicated set of movements. Therefore, this statement must be FALSE. |

Q10 The honeybee dance is performed until a number of other bees join in the collection of the nectar. |
She will repeat this pattern, which von Frisch’s team called the round dance, until she has recruited several other workers to return with her to the field. |
Unless other bees join her, the bee will repeatedly perform the round dance. In other words, the honeybee dance is performed until a number of other bees join in the collection of the nectar. Therefore, this statement is TRUE. |

Q12 Wenner concluded that a matching smell will help bees find the rough area of the nectar but not the specific source. |
Using robotic bees to perform the same dances, Wenner was unable to attract new recruits to the foraging activities; however, when he added a bit of nectar to the robot, workers quickly followed. He also discovered that the odors must be representative of the actual flowers containing the food source; otherwise the bees will arrive at the site, but not know which ones will be profitable. |
Through his experiment, Wenner discovered that the odour must be representative of the actual flowers containing the food source. If the odour is appropriate, the bees will figure out the specific location of the flowers containing the source. In other words, a matching smell will help bees find the specific area of the nectar, which makes this statement FALSE. |
