Answer:
Option (4) is the correct answer.
Explanation:
In Java programming language ,array collection starts from 0 index location and ends in a size-1 index location. So to access the last elements the user needs to use a[Size-1] statement. so to modify the value of the last location of the array the user needs to use "a[size-1]= element;".
But when the user wants to add some new value to the end of the array list collection then he needs to use the statement--
a.add(element); //where add is a function, element is a value and a is a array list object.
Another option is invalid because--
- Option 1 is not the correct because "a[3]=element;" modify the value of the 3rd element of the array.
- Option 2 gives a compile-time error because add functions bracts are not closed.
- Option 3 gives the error because a[4] gives the location of the 5th element of the array but the above question says that a is defined with 4 elements.

Answer:
Crisis-Mapping
Explanation:
Social networks are characterized by the immediacy of the content that users produce, and that same feature can be transferred to the online mapping of crises and conflicts.
Characteristics Crisis-Mapping:
- Real-time information processing.
- Immediacy;
- Visualization of the aggregated information can allow the detection of patterns that cause new analyzes to be undertaken or work hypothesis to verify.
- Continuity in the tasks, the maps record activity without interruption during the twenty-four hours of the day and seven days per week.
-
Flexibility in the protocols, since the tasks are distributed and evolve according to the dynamics (the crisis maps evolve with the crisis itself).
Update and measure those are the only understand answers
