The computer worked fine until I began playing music through it. Then it slowed down to a halt and froze. It was really frustrating. I just wanted it to work!

Explanation:

This is what we need to know about the Simple Past Tense to answer this question.

2. Regular verbs in the past will have -d, -ed, or -ied added to their ending. The ones that end in e receive -d. The ones that end in consonant + y drop the -y and receive -ied. And the rest receives -ed.

3. Irregular verbs in the past have each a different form. There isn't much we can do but memorize them. For example: begin - began; freeze - froze; go - went; speak - spoke.

Why do you think space exploration is important?

What do you think the world will be like in 100 years?

Why do you share photos on social media?

Explanation:

The three questions I chose are all open-ended because they can't be answered with a simple "yes" or "no". If you ever have a question like this again, remember: Open-ended questions mean the answer couldn't be "yes" or "no".

For example, "Do you think that panda bears  are cute?" can be answered with a "yes". If you want it to be open-ended, it'd have to be "Why do you think that panda bears  are cute?".

Tip: Open-ended questions usually start with "Why" or "What" (as those would need explanation, while a question that starts with "Do" or "Would" can probably be answered with a simple "yes" or "no").

Answers

Answer and Explanation:

1. The author shows that education without purpose and without instructing a trade is not an education. This is because education should allow the focus on the world around them, promoting racism and the resolution of problems in society, however, the education that is mentioned in the article, which only promotes concentration on reading, does not promote these skills and therefore , cannot be considered an education.

2. Because he believes that this type of education does not make any progress for humanity and serves only as a purposeless appearance.

3. An education must promote progress, reasoning, proactivity and work that helps society to move forward. Without it, education is useless.

4. All people must be educated the same way, when education is done with the proposed objectives aicma, as it would create a completely active and rational society.

I have a paragraph and I want to add some words to it. Is there someone to help me?

Answers

Answer:

Depending on what you are writing, I'd suggest using "Domain Specific words". These types of words are words that fit into a certain subject. For example, if you're writing about English, you could say things like "theme", "symbolism", etc.. Though, domain specific words are more so for sounding professional. To actually add words, try and slip in some transition words, which are words like "meanwhile", "thus", "due to", "afterward". Some other words you can add are describing words, also known as adjectives. So maybe if you're describing an animal, add words like "sharp" to describe claws, and things like that. There are many other things you can add, which just revise your paragraph and look at where it seems you can add words and maybe fix up your wording. If you'd like to tell me a bit about what you're writing, I can help you out better. ^^

Lydia is a senior in high school. She works 20 hours a week at a popular clothing store. She is trying to save as much money as possible for her college tuition. However, she has to buy a dress for prom, pay her car insurance, and get a birthday gift for her sister. This week she received a $400 paycheck. She wants to deposit the entire check in her savings account for her college tuition, but she stops herself. She decides instead to put $100 in the bank, spend $200 for her prom dress, pay $80 for her car insurance, and buy her little sister a $20 birthday gift. While shopping, she sees a doll worth $21, which she thinks her sister will absolutely love. As a result, she decided to buy the more expensive doll and spend less on her dress.

The following question references the novel The Call of the Wild by Jack London.

Explain the "call of the wild".

Answers

Answer:

The Call of the Wild is a short adventure novel by Jack London, published in 1903 and set in Yukon, Canada, during the 1890s Klondike Gold Rush, when strong sled dogs were in high demand. The central character of the novel is a dog named Buck. The story opens at a ranch in Santa Clara Valley, California, when Buck is stolen from his home and sold into service as a sled dog in Alaska. He becomes progressively primitive and wild in the harsh environment, where he is forced to fight to survive and dominate other dogs. By the end, he sheds the veneer of civilization, and relies on primordial instinct and learned experience to emerge as a leader in the wild.

London spent almost a year in the Yukon, and his observations form much of the material for the book. The story was serialized in The Saturday Evening Post in the summer of 1903 and was published later that year in book form. The book's great popularity and success made a reputation for London. As early as 1923, the story was adapted to film, and it has since seen several more cinematic adaptations.
