Answers

Answer 1

A practical advantage of a surrogate key is that values for it can be generated by the DBMS to ensure that unique values are always provided. The statement is true.

What is a surrogate key?

A surrogate key is a type of key in database design that is often used to uniquely identify a record in a table, usually in replacement of a natural key (a column or set of columns that uniquely identifies a record in a table).A surrogate key is a unique value that is used to identify each row in a table uniquely. Surrogate keys are used in databases to ensure that each row has a unique identifier.

These keys are automatically generated by the database management system (DBMS) as a result of an algorithm or by simply incrementing a counter. Surrogate keys are often used instead of natural keys because they are more stable, less complex, and less prone to change over time. Surrogate keys are sometimes called "artificial" keys.

What is the advantage of using a surrogate key?

One of the practical advantages of a surrogate key is that because it has no intrinsic meaning, values for it can be generated by the DBMS to ensure that unique values are always provided. This eliminates the need for developers to maintain a separate table or column of unique values.

Additionally, surrogate keys can be used to speed up searches and increase database performance by minimizing the amount of disk I/O required to perform a search. This is because surrogate keys are typically smaller than natural keys and can be stored more efficiently. Therefore, the correct answer is a surrogate key.

Mark does not study for an exam and consequently flunks it. Mark confronts his professor and explains that he expects a higher grade because he "deserves" great grades. How would Freud classify Mark?

Answers

According to Freud, Mark would be classified as being in the oral stage, which is the first stage of psychosexual development. The oral stage is the first stage of psychosexual development, according to Sigmund Freud.

Oral stage occurs in the first year of a child's life and is characterized by an emphasis on oral gratification. The child obtains pleasure through oral activities such as breastfeeding, and the sucking reflex becomes a point of focus. The weaning process and the development of the ego are two significant events in the oral stage.

Freud believed that when an individual is fixated on the oral stage, he or she is more likely to have an oral personality. This personality type is characterized by the need for oral stimulation and excessive reliance on oral activities for comfort. Mark's behavior can be seen as a sign of his fixation on the oral stage because he is unable to control his need for pleasure and lacks the ability to take responsibility for his actions. His inability to control his desires causes him to fail the exam, and his lack of responsibility for his actions causes him to expect a higher grade than he deserves.

Answers

Bloom states that people are naturally more likely to believe in creationism than evolution. This can be explained by the phenomenon of Cognitive Bias.

What is Cognitive Bias?

A cognitive bias refers to the tendency of human beings to process information subjectively based on their individual experiences and cognitive predispositions. When individuals receive data that is consistent with their preexisting beliefs, they tend to remember it more efficiently and consider it to be more important than information that contradicts their beliefs.

As a result of this cognitive bias, people tend to be more inclined to believe in creationism than in evolution because it aligns with their beliefs, making it easier for them to process information that supports this viewpoint. Bloom's hypothesis is consistent with research that has shown that people's beliefs about controversial issues such as evolution and climate change are often shaped by cognitive biases.

The given statement "we are especially likely to vicariously experience the reinforcing outcomes of those we perceive as similar to ourselves"  

A person who has similar characteristics, attitudes, and behavior to ourselves is more likely to influence us. It is because we can relate to the person and thus learn and adopt their behaviors easily. However, we may also be influenced by people who are not like us but possess desirable qualities that we would like to acquire.

These people serve as role models and motivators to us. Antisocial models, extrinsically motivated, and latent learners are not necessarily factors that determine whether we can vicariously experience the reinforcing outcomes of others we perceive as similar to ourselves.  

When we can see ourselves in someone else, we are more likely to be inspired and motivated to emulate their successes. This is because we feel that if they can succeed, then we can also do it.

Answers

Single-mode fiber would be the best choice of physical medium to connect two offices that are 21 kilometers, or 13 miles, apart from each other. Single-mode fiber is designed to transmit data over long distances with high bandwidth and low signal attenuation, making it an ideal choice for long-haul telecommunications.

The physical medium that would be the best choice to connect two offices that are approximately 21 kilometers (13 miles) apart from each other is single-mode fiber. Single-mode fiber Single-mode fiber (SMF) is a type of optical fiber that is used to transport a single light beam (mode) along the fiber over long distances. SMF can only carry a single mode of light, which means it can only transmit one ray of light. SMF has a small core diameter of around 9 microns, which means it is capable of transmitting light over long distances without dispersion.

Twisted-pair Ethernet cabling and coaxial cabling have distance limitations and are not suitable for long distances over 10 km. Multimode fiber is better suited for shorter distances and has a lower bandwidth and higher attenuation than single-mode fiber. Therefore, single-mode fiber is the best choice for connecting two offices that are 21 km apart.

Therefore, SMF is best suited for high-speed, long-distance communications that require low attenuation (signal loss). SMF is the most commonly used physical medium for connecting two far-off locations. The answer is C. Single-mode fiber.

What should be done when a driver encounters a strong gust of wind?

When a driver encounters a strong gust of wind, it is important for the driver to remain calm and maintain control of the vehicle. The driver should grip the steering wheel firmly with both hands and try to keep the vehicle in its lane. The driver should not panic or overcorrect, as this could cause the vehicle to swerve or lose control.

If the wind is particularly strong, the driver may need to slow down or even pull over to a safe location until the wind subsides. It is also important for the driver to be aware of any potential hazards on the road, such as fallen trees or debris, which could be caused by the strong winds.

Which of the following statements, if true, would most directly challenge the principles of formalist criticism?A. the capacity to interpret a work of literature varies from reader to readerB. good literature is more than just effective rhetoricC. Knowledge of the author's intentions is not usually reliableD. The social and historical contexts of a work of literature cannot be ignored

Answers

If true, would most directly challenge the principles of formalist criticism is the social and historical contexts of a work of literature cannot be ignored, option D is correct.

The social and historical contexts of a work of literature cannot be ignored. Formalist criticism is based on the idea that a work of literature should be judged on its own terms without reference to the external circumstances in which it was written.

This means that the social and historical contexts of a work are not taken into consideration. Therefore, a statement which acknowledges that these contexts can't be ignored would directly challenge the principles of formalist criticism.

The statement which would most directly challenge the principles of formalist criticism is "Knowledge of the author's intentions is not usually reliable". Formalism is an approach to literary criticism that emphasizes the formal aspects of a work of literature.

It emphasizes the form, structure, tone, imagery, and literary techniques used in the work of literature. The literary work is seen as a self-contained entity with its structure and organization as the primary focus of the reader. Formalism was introduced in the early 20th century by Russian Formalists, who wanted to distance themselves from historical and cultural contexts.

The principles of formalist criticism include close reading of the literary work, focusing on the form, structure, tone, imagery, and literary techniques used in the work of literature. It emphasizes the self-contained nature of the literary work, without regard to historical or cultural contexts.

The statement which would most directly challenge the principles of formalist criticism is "Knowledge of the author's intentions is not usually reliable". This statement suggests that the author's intentions should be taken into account while analyzing the literary work, which goes against the principles of formalist criticism.
