A statement which best illustrates the relationship between entities and attributes is: B) the entity CUSTOMER with the attribute PURCHASE.
<h3>What is an entity relationship?</h3>
An entity relationship can be defined as a data model with the highest level of abstraction and it is typically designed and develop to avail designers or programmers (end users) an ability to use a graphical tool to examine structures rather than describe them by using text.
<h3>What is an attribute?</h3>
In Computer technology, an attribute can be defined as a unique characteristic or quality which primarily describes an entity in a software program.
In this context, we can infer and logically deduce that a statement which best illustrates or shows the relationship between entities and attributes is the entity "CUSTOMER" with the attribute "PURCHASE."

The scientists ensure that their results are reliable by repeating trials.
Given that scientists ensure that their results are reliable.
We are required to tell the way how scientists ensure that their results are reliable.
Reliability is basically defined as the probability that a product, system, or service will perform its intended function adequately for a specified period of time, or will operate in a defined environment without failure.
Reliability increases from repeating trials.It is like vaccines. Firstly the trials to be made on small number of persons, then the numbers increases and then ultimately the trials are done on the large number of persons.
Hence the scientists ensure that their results are reliable by repeating trials.
