1 In the context of the Hawk-Dove game, what does a 'Hawk' strategy represent?

A Aggressive fighting until victory or injury
B Consistently sharing resources equally
C Fleeing immediately upon spotting a competitor
D Attempting to resolve conflicts through displays

2 The concept of an Evolutionarily Stable Strategy (ESS), coined by John Maynard Smith, describes a strategy that:

A Can be learned by all individuals in a population
B Cannot be successfully invaded by alternative strategies
C Ensures the survival of the individual indefinitely
D Always results in the highest possible population density

3 Which phenomenon in nature is often modeled using the 'Prisoner's Dilemma' to explain the evolution of cooperation?

A Predation on solitary prey
B Mutual grooming in primates
C Individual camouflage
D Migration patterns

4 In 'Tit-for-Tat' strategy, an animal's next move is determined by:

A Random chance
B The opponent's previous action
C The total resources available
D Its own genetic dominance

5 The 'War of Attrition' model is most often used to explain animal behavior during:

A Migration across continents
B Contests over mates or resources where cost is time
C Foraging in nutrient-poor environments
D Establishing dominance hierarchies through size

6 Why is 'altruism' in social insects like honeybees considered a game-theoretic puzzle?

A It requires higher-level intelligence
B It seemingly contradicts individual fitness maximization
C It only occurs in artificial environments
D It is a myth unsupported by genetic data

7 The 'Tragedy of the Commons' in ecology frequently occurs when:

A Resources are overexploited by individuals acting in self-interest
B Predators go extinct due to lack of prey
C The environment remains pristine
D Species evolve to be exclusively herbivorous

8 What is the primary factor that makes the 'Iterated' Prisoner's Dilemma different from the one-shot version in nature?

A The reduction of total population size
B The potential for future interaction and retaliation
C The presence of multiple predators
D The change in climate conditions

9 In signaling theory, the 'Handicap Principle' suggests that honest signals of quality are:

A Easy to fake by weak individuals
B Costly to produce, ensuring they are reliable
C Only used by nocturnal species
D Purely accidental genetic mutations

10 A 'Mixed Strategy' equilibrium in biological games occurs when:

A An individual changes its strategy during a single fight
B Individuals choose between different strategies with specific probabilities
C All members of a species act exactly the same way
D The population size stays constant

11 Which evolutionary game theory model explains why some animals share food despite the immediate cost to themselves?

A Kin selection
B Sexual dimorphism
C Niche partitioning
D Genetic drift

12 In the 'Scramble Competition' model, what determines the success of an individual?

A Fighting ability
B Priority of access or speed in acquisition
C Ability to signal strength
D Agreement on territory lines

13 The 'Dear Enemy' effect in territorial animals is a game-theoretic observation where neighbors:

A Attack each other constantly
B Show reduced aggression toward familiar individuals
C Migrate away from each other immediately
D Share offspring

14 What is the stable result in a 'Coordination Game' between two species living in mutualistic symbiosis?

A Both species defecting simultaneously
B Both species providing benefits to the other
C One species consistently dominating the other
D Periodic extinction of both species

15 Why do many species engage in ritualized combat rather than all-out fighting?

A They lack the physical capacity for violence
B The cost of injury outweighs the benefit of winning
C They are constrained by environmental law
D They possess altruistic morality
