The correct answer is Systematic observation
Systematic observation is a method used to understand how a particular activity or task works. The researcher observes the steps of a process, the tools used, the difficulties that appear, the conversations and results of the work.
Systematic Observation is guided by a defined objective, something you want to know about that activity. The observation is made repeatedly until there is sufficient evidence to state this.
Systematic Observation can be used to do Behavioral Mapping, Task Analysis or Activity Analysis.

Answer: Universal grammar
Explanation: The concept or theory of universal grammar credited to Noam Chomsky simply argues that; The human brain is composed or consists of naturally structural set of rules upon which an individual develops his/her language skills, irrespective of the individual's language. It explains that there is a basis upon which any individual develops his language skill and this basis which is a structured set of skills is innate. A close instance is a child's ability to learn it's native language at such a tender age, supporting the existence of a developed genetic structure suitable for language development.
