Answer:

Explanation:

Hello!

The research hypothesis is that "The new advertisement increases the likelihood of people buying the new  mechanical toy dogs"

The new campaign is designed to be persuasive to people with a certain personality profile.

To test her hypothesis, the doctor choose 4 groups of participants and asked them whether they were interested in acquiring the toy before and after watching the advertisement.

The clear limitation in this trial is the failure of taking a representative sample. There are several confounding factors not taken into account, such as social status of the participants (if they can or cannot afford the toy), family status (people with children are more likely to buy toys than childless adults).

It is possible that the people assigned to each group had different propensity for acquiring the toys and that these groups  were unbalanced, producing bias in the conclusions extracted from this trial.

I hope this helps!

The repetition of versions of the word “like” at the end of each line of the poem does all of the following EXCEPT
Readme [11.4K]

Answer:

E. suggests that the speaker's vocabulary is limited

Explanation:

The question above is related to the poem entitled "Sestina: Like," written by A.E. Stallings. It is a fixed verse type of poem which consists of<em> six stanzas.</em> Every stanza has<u> six lines. </u>

The repetition of versions of the word "like" at the end of the lines allows the poem to focus on its subject matter. This allows the central concept of the poem to be unified. It also shows that the poet used the word "like" as a play on words because it provides "humor" to what is happening in the society today.

So, this concludes that <u>using the word "like" doesn't mean the poet has a limited vocabulary.</u>

Thus, this explains the answer.

A. Describe TWO ways that the process of globalization has contributed to similarities between the cultural landscapes shown in
nata0808 [166]

One way of technology advancement that has led to similarities in the two pictures is the idea of long-lasting lights or LED lights. In the pictures, both cities have numerous big TV ads that require a lot of light to make sure it stays bright and appealing. Through the invention of LED lights, light bulbs can now last longer and won’t have to worry people about frequently changing light fixtures. This allows for the bright lights advertisements in New York City and Tokyo. Another technological advancement in both photos is the fact of how both landscapes came to look like each other. This is through advances in communication such as social media and television. The popular landscape of Times Square in New York was definitely posted on the internet or showcased on the news and people around the world found it fascinating. The City of Tokyo then decided to have Shibuya Crossing look the same too to attract tourists as well. The cultural pattern of Times Square then diffused to other cities. Advances in communication technology has caused similarities in many cultural landscapes, especially from New York City to Tokyo.

Increased internet access has contributed to convergence in cultures through many platforms such as social media and messaging. When different countries all have access to the same internet program, people from each country can communicate and converge their cultures. For example, popular posts on social media of a fashion trend in Japan can lead to the same fashion trend in the United States. And since other countries can also see that post on the internet, they might start to follow that fashion trend too. The Japan fashion culture has then diffused through many parts of the world because more people across the globe have increased internet access.

The way an ethnic food can become popular in menu items across the globe is thorough relocation diffusion. An ethnic food may be introduced to a new country and the people there will come to like it and possibly to change to their preferences. For example, pizza was a dish invented in Italy, therefore it is an ethnic food for Italy. People from different parts of the world came to Italy, tried the pizza, and decided to have that meal in their country too. Pizza is now very popular, especially in the United States and people in the United States have also changed the pizza and made other flavors like Hawaiian for their liking. A widespread menu item becomes popular also by stimulus diffusion, since people are changing the original recipe of the pizza and making it gluten free or vegan. Any ethnic food can become a popular global dish by relocating to another country and satisfying the people there with that particular dish.

A cognitive psychologist conducts a study to examine differences in cognitive functioning across stages of adulthood. He opts to  study one group of young adults ages 21-28. one group of middle-aged adults aged 41-48, and one group of older adults ages 61- 68- The psychologist finding that  that the middle age  group outperforms the older group is a valid criticism to the study's conclusion

Explanation:

A cognitive psychologist concludes that age relates to cognitive performance on these tasks.This statement means that as a person age's its ability to perform the cognitive task declines .In the study conducted between the various age group the cognitive psychologist where able to find that the people in their middle age (i.e. between 41-48) were able to perform the cognitive task is a better way than the people in the older group. and the younger group was able to perform the cognitive task much better than the middle and the old age group.

Now their is no need for the  comparison of the middle age and the old age people for performing the task because as er the conclusion the cognitive skills decline with the age.

So,the psychologist finding that  that the middle age  group outperforms the older group is a valid criticism to the study's conclusion
