Answer:
I. Algorithms can be written using pseudocode.
II. Algorithms can be visualized using flowcharts.
Explanation:
An algorithm can be defined as a standard formula or procedures which comprises of set of finite steps or instructions for solving a problem on a computer. The time complexity is a measure of the amount of time required by an algorithm to run till its completion of the task with respect to the length of the input.
The two statements which are true about algorithms are;
I. Algorithms can be written using pseudocode. A pseudocode refers to the description of the steps contained in an algorithm using a plain or natural language.
II. Algorithms can be visualized using flowcharts. A flowchart can be defined as a graphical representation of an algorithm for a process or workflow.
Basically, a flowchart make use of standard symbols such as arrows, rectangle, diamond and an oval to graphically represent the steps associated with a system, process or workflow sequentially i.e from the beginning (start) to the end (finish).

Tier 1 support
Explanation:
Of the given options, tier 1 support technical group is the least experienced group. This group of technicians is also referred to as level 1 technical group.
The tier 1 or level support are made up of junior technician, and they have few technical understandings.
Their roles include email response and basic troubleshooting, attending to phone calls, among others.
When a problem cannot be solved by tier 1 support technicians, they pass the problem to tier 2 support technicians,
