Science I think if that’s a choice??
Hi!
Your answer is B.
It is <u><em>not</em></u> A because this doesn't really make sense. It's not the best answer.
It <u><em>is</em></u> B because, in sentences, the words around it will likely give the information you need to infer what the word means.
(For example, if I were to say "<em>She was </em><u><em>continuously</em></u><em> singing, for yesterday she sang for 4 straight hours, and it was extremely annoying</em>", pretend you do not know what "continuously" means. By using the words around it, such as "4 straight hours" you can predict that it means "never stopping".)
It is <u><em>not</em></u> C because not every single sentence contains a synonym or antonym.
(See the sentence above. The antonym of "continuously" would be 'never' or 'sometimes' or possibly 'discontinous'. There isn't always an antonym or synonym there, is there?)
It is <u><em>not</em></u> D because not every single word is defined in a passage.
(When you open an average book, is there just an entire page(s) dedicated to every single definition of a word? Most often, no, there is not.)
Enumerated powers are enumerated in some kind of document.
Implied powers are not specifically enumerated in some kind of document, but they would be necessary to fulfill some responsibility.
The answer is Count. Count is an aggregate method in SQL that returns the number of rows for a specified column that have non-null values.
<h3>What is the Meaning of Null?</h3>
When a field in a database has no values at all, this is known as null and indicates that the field’s value is unknown.
A null value for a number field, text field, or space value is different from a zero value. Null indicates that no value has been recorded in a database field.
A value and a null cannot be compared. The Structured Query Language query cannot be written as SELECT * FROM Customer where email Address=null, for instance, if it is intended to obtain all customers without email addresses from a Customer Addresses table.
