Answer:
The correct answer is herd immunity.
Explanation:
Herd immunity is the resistance against a contagious disease provided by the immune individuals which makes the major part of the population to few susceptible individuals in the community.  
So as most of the population is immune to the disease therefore that disease is not able to overpass these immune individuals and the susceptible person is protected indirectly from that contagious disease. By vaccinating most of the people against a disease we can gain herd immunity. So the right answer is herd immunity.
 
        
             
        
        
        
Answer:
The correct answer is option (3) Complex.
Explanation:
The complex reaction time is a stimulus response. The complex reaction time may be defined as the latency that exists between the variable response and the variable stimulus.  It decides the arrival of the stimulus and the time required to generate the response. The fatigue and type of stimulus may affect the reaction time.
Further explanation:
- Reaction time may be defined as the time required for the onset of any stimuli and the emission response of an organism.
- Simple reaction time is the only time that is taken to react towards a stimuli.
- The reaction time can be affected by various factors like age, gender, sex, race, stimulus type, stimulus intensity and psychological stability.  
- Complex reaction time takes more time than the simple reaction time as they store the information for longer time.  
- The information processing and transmission of the information of a particular stimuli can be measured in terms of the reaction time.
- The visual stimuli, auditory stimuli strength and its generation time response can be calculated by the reaction time.

The first answer is true in the sense that these two sports are individual from one another, but it is false in the sense that both these sports are team sports (not just one person is playing).
The second answer is false. For example, if I'm running a 5k without ever having run one before, I'm not sure how long it will take me to finish.
The third answer is true. Swimming is a great exercise that will increase lung capacity and thus improve respiratory health.
The fourth answer is true. A scale will only tell you numbers; it cannot determine what your healthy/comfortable weight is. 
The last answer is true. By practicing an activity more, you will become better at it.
