donald trump won a razzie award for worst supporting actor for his cameo appearance in which film?

Answers

In the year 1991, Donald Trump won a Razzie Award for Worst Supporting Actor for his cameo appearance in the film "Ghosts Can't Do It".

The film was a fantasy comedy-drama film directed by John Derek and starring Anthony Quinn and Bo Derek. Trump's cameo appearance in the film was a brief part in which he played himself, in a scene where he attended a party thrown by Quinn's character. The scene was only a few minutes long, and Trump did not have any lines, but he was seen standing in the background.

The film received largely negative reviews, and Trump's cameo was no exception. Critics were particularly unimpressed by Trump's lack of charisma and presence in the scene, and his performance was seen as one of the worst of the year. As a result, Trump was nominated for and won a Razzie Award for Worst Supporting Actor.

Though Trump has not acted in any other films since then, he has been the focus of many other films, documentaries, and television shows. His life and career have been the subject of much scrutiny and debate, and his continued presence in the public eye has made him one of the most recognizable figures in the world.

4. Is this artwork mysterious, boring, or exciting?
5. What do you think happened next or before this scene?

Answers

Answer:

What's going on in this artwork?

This artwork is an ancient Egyptian tomb painting, depicting the god Anubis guiding the deceased person's soul to the underworld for judgment. The painting shows the deceased person's soul, represented by the bird-like figure, being led by Anubis, who is depicted as a jackal-headed figure.

How would you describe this artwork to someone who has never seen it?

This artwork is a colorful painting on a wall in a tomb. It shows a jackal-headed figure leading a bird-like figure. The figures are in front of a big building with several pillars and two other figures standing in front of the building. The background is a beautiful blue with stars.

Which area of the artwork is most important? Why?

The most important area of this artwork is the figures of Anubis and the soul because they are the main subject of the painting and convey the central message of the painting which is the guiding of the soul to the underworld. It is significant because the ancient Egyptians believed in afterlife and the painting is meant to guide the deceased person's soul on the journey to the underworld.

Is this artwork mysterious, boring, or exciting?

I would say this artwork is mysterious. The depiction of the underworld and the journey of the soul after death is a mysterious concept, and the art itself gives a glimpse of what ancient Egyptians believed about the afterlife. The details in the painting and the vibrant colors used make it an intriguing work to look at.

What do you think happened next or before this scene?

It is difficult to say exactly what happened before or after this scene, as it is a single moment captured in the painting. However, it is likely that the scene depicts the soul's journey to the underworld and the judgment that takes place there. This scene may be part of a larger narrative that tells the story of the deceased person's journey to the afterlife, or it may be one of several scenes that together, give an overall view of the ancient Egyptian belief in the afterlife.

During the Baroque, the differences between the art produced in the north and south of Europe were less ones of style and more ones relating to subject matter and attitudes to religion. Which of the following paintings was created by a northern European artist and which by a southern European one

Answers

During the Baroque period, northern European artists such as Rembrandt and Rubens were known for their use of light and shadow to create dramatic, emotional scenes. They often depicted religious and mythological subjects with a strong sense of movement and drama, and their paintings often had a strong sense of realism and naturalism.

On the other hand, southern European artists such as Caravaggio and Bernini were known for their use of strong contrasts of light and dark, and for their use of dramatic poses and gestures. They often depicted religious subjects in a more stylized, idealized manner, and their paintings often had a sense of grandeur and grandiosity.

A northern European Baroque painting would be Rembrandt's "Night Watch" which is a large group portrait, while a southern European Baroque painting would be Caravaggio's "The Calling of Saint Matthew", which is a dramatic scene of a religious figure.

if you approach an intersection at which the traffic lights are not working, you must first before entering the intersection and then yield the right of way

Answers

If you approach an intersection where the traffic lights are not working, you must first come to a complete stop before entering the intersection and yield the right-of-way.

In a lot of cases, stop signs are placed at intersections in which visibility may be impaired (either by the road we are on or by cars approaching on other roads), so it is important to come to a complete stop so we and other drivers have time to react.

What is the right thing to do when we approach an intersection?

The first thing we have to do when we arrive at an intersection is yielding to vehicles already in the intersection or about to enter it. We have to yield to the vehicle on our right if it has reached the intersection of same time as our vehicle. We also need to stop at any limit line or crosswalk.

A driver who arrives at an intersection have to yield the right-of-way to traffic which is in the intersection. If drivers approaching from opposite directions reach an intersection at about the same time, a driver who turns left need to yield to traffic which moves straight or turns right.

Name and describe three major elements of composition commonly found in Baroque music.

Answers

BAROQUE MUSIC

Three major elements of composition commonly found in Baroque music are:

Polyphonic texture: This refers to the use of multiple independent melodic lines that are played or sung simultaneously. Polyphonic texture was a common feature of Baroque music and was often used to create complex, ornate musical structures.

Ornamentation: Baroque music is known for its use of ornamental flourishes and decorations, such as trills, turns, and mordents, which were added to the melodies to add interest and variety.

Ritornello form: This is a musical form in which a short musical passage, called the ritornello, is repeated multiple times throughout a composition. Ritornello form was commonly used in Baroque music, especially in instrumental works, and was often used to provide structural unity to a piece.

These elements of composition helped to define the Baroque style and contributed to the elaborate, ornate character of much of the music of this period.

Elion received the Nobel prize for medicine in 1988 along with George H. Hitchings and Sir James W. Black. The three were awarded the prize for their development of drugs used to treat several major diseases.Gertrude Belle Elion was born on Jan. 23, 1918, in New York City. She graduated from Hunter College in New York City with a degree in biochemistry in 1937. Unable to obtain a graduate research position because she was a woman, she took a series of jobs, including lab assistant, chemistry and physics teacher in New York City high schools, and research chemist. During this time she also took classes at New York University, where she earned a master's degree in 1941. Because she could not devote herself to full-time studies, Elion never received a doctorate.In 1944 Elion joined the Burroughs Wellcome Laboratories (now part of GlaxoSmithKline (a company that makes prescription medicines)). There she was first the assistant and then the colleague of Hitchings, with whom she worked for the next four decades. Elion and Hitchings developed an array (variety) of new drugs that were effective against leukemia, autoimmune disorders, urinary-tract infections, gout, malaria, and viral herpes. Their success was due primarily to their innovative (characterized by new or unique) research methods. Rather than using the trial-and-error approach used by previous pharmacologists, Elion and Hitchings examined the difference between the biochemistry of normal human cells and that of cancer cells, bacteria, viruses, and other pathogens (disease-causing agents). They used this information to create drugs that could target a particular pathogen without harming the human host's normal cells. Their methods enabled them to eliminate much of the guesswork and wasted effort typical in previous drug research.Although Elion officially retired in 1983, she helped oversee the development of azidothymidine (AZT), the first drug used in the treatment of AIDS. In 1991 she was awarded a National Medal of Science and was inducted into the National Women's Hall of Fame. She died on Feb. 21, 1999, in Chapel Hill, N.C.Student J.
