statuscvo [17]

Answer: The Necessary and Proper Clause gave it relevance and the amendment process gave it flexibility.

Explanation:

The United States of America consist about seven thousands words. The "Necessary and Proper" Clause can be found in Article 1 on the right section of the constitution. The article states and I quote:

''...to make all Laws which shall be NECESSARY AND PROPER for carrying into Execution the foregoing Powers, and all other Powers vested by this Constitution in the Government of the United States, or any Department or Officer thereof".

NOTE: The words in block/capital letters identify the clause.

The Necessary and proper clause is also reffered to as an Elastic clause.

Also, the Amendment process makes the constitution flexible. The constitution can be amended if the majority (two-thirds) votes for an amendment in the constitution.

characteristic of the Constitution has kept it relevant and flexible, by virtue of very general language is the NECESSARY AND PROPER CLAUSE.

fiasKO [112]

The correct answer to this open question is the following.

Although the are no options attached, we can say the following.

When looking back at the course of her relationship, Helga realized that she has not been happy with her boyfriend's behavior for quite some time. Helga is taking into account the aspect of the social exchange theory known as reciprocity or the expectations of the relationship.

That is why Helga considers that his boyfriend's behavior is not reciprocal to Helga's. Helga was expecting more of her boyfriend but probably his expectations are not the same as Helga's. That is why he seems not to be committed as Helga is. This social exchange theory assumes that people are in a relationship to maximize their satisfaction because relationships produce great gratification.
