Unclear question. However, here's the clear rendering;
"Explain the situation and the circumstances behind the emergence of economics? it is clear 3 (three) economic concepts below, namely: scarcity, choice and alternative costs".
Explanation:
Remember, the widely accepted definition of economist is that of Lionel Robbins. Noteworthy in his definition is that scarcity creates a need to decide how best to manage resources.
Scarcity: the lack of needed resources.
Choice: the decision or action taken to satisfy our wants.
Alternative cost: are other cost options available to choose from.
Answer:
Absolute
Prepositional
Participial
Explanation:
A subordinate CLAUSE (not phrase) contains a subject and verb, is introduced by a conjunction, and supports the main clause.
An absolute phrase combines a noun and a participle. (e.g. shining stars, crossed arms)
A prepositional phrase is a modifying phrase consisting of a preposition and its object. (on the table, beside the stairs)
A participial phrase will begin with a present or past participle and will always function as an adjective, describing a nearby noun or pronoun.
(e.g. PUTTING ON HER BOOTS, she trudged into the snow.)
Answer: What is the goal of the presentation?
Explanation:
I would ask this first because the most important thing in your presentation is what your goal is and what you want to accomplish. Without knowing what your goal is, you will not be able to focus on the other things you mentioned.
