+# --description--
+
+Prepositions are words that link nouns, pronouns, or phrases to other words within a sentence and often indicate time, place, or relationship, like `with`, `for`, `about`. They can also appear at the end of a question or sentence, which is common in spoken English.
+
+Examples:
+
+When someone asks `who are you going with?` the preposition `with` is used at the end to inquire about the company one will have.
+
+`What are you excited about?` In this question, `about` is used at the end to inquire regarding the subject or event that is causing excitement.
+
+`Who are you waiting for?` Here, `for` is placed at the end of the question to ask about the person for whom someone is waiting.
+

+
+Which sentence correctly uses a preposition at the end?
+
+## --answers--
+
+`What are you speaking of?`
+
+### --feedback--
+
+While `of` is a preposition, this sentence sounds a bit awkward or formal. It would be more natural to ask, `What are you talking about?`
+
+---
+
+`What are you looking for?`
+
+---
+
+`Where is it belong?`
+
+### --feedback--
+
+The correct sentence should be `Where does it belong?` without the preposition at the end, as `belong` does not typically require a preposition.
+
+---
+
+`Who do you want to meet with she?`
+
+### --feedback--
+
+The correct form should be `Who do you want to meet with?` `With she` is grammatically incorrect; it should be `with her`.

+In programming, `int` stands for "integer". It's a data type used to store whole numbers, which are numbers without fractional parts or decimals. Integers can be positive, negative, or zero.
+
+Choosing the `int` data type is essential when dealing with whole numbers, like counts, indexes in arrays, or any scenario where fractional numbers are not needed.

+
+Counting items: `int itemCount = 5;`

+This task focuses on the relative pronoun `that`. It is used to introduce a clause providing more details about a noun.
+
+A "clause" is a part of a sentence that contains at least a subject and a verb. It can express a complete idea or add extra information to the main sentence.
+
+The pronoun `that` helps specify or define something more clearly, connecting it to a description or a necessary detail.
+
+For examples, `She read the book that won the Pulitzer Prize last year.` In this sentence, `that won the Pulitzer Prize last year` is a relative clause introduced by `that`. The clause describes or specifies the book, helping to distinguish it from other books. Here, `that` acts as a relative pronoun connecting the clause to the noun `book`, and it describes which particular book she read.

+Direct questions are straightforward inquiries that clearly ask for specific information. They typically invert the subject and the verb, like in `Are you sure?` This form is commonly used in everyday conversations, especially when quick and clear answers are needed.
+
+Indirect questions or statements, on the other hand, are more polite and less direct. They do not invert the subject and the verb and often begin with phrases like `I was wondering` or `Could you tell me`. For example, instead of asking `Where do you live?` you might say, `Could you tell me where you live?` This makes the question sound less abrupt and more polite, which is particularly useful in formal settings or when you're speaking with someone you don't know well.

+The word `what` can be used to introduce a clause. It typically introduces noun clauses, providing more information about a noun or acting as a part of a statement.
+
+A noun clause is a clause that functions as a noun within a larger sentence. It typically includes a subject and a verb, and can act as the subject, object, or complement in a sentence.
+
+For example, in the sentence `She doesn't know what to buy`, `what to buy` is a clause where `what` stands for the thing that she needs to decide on purchasing.
+
+Another example is `Tell me what you heard.` `What you heard` is the clause, with `what` explaining the specific things that were heard, acting as the object of the verb `heard`.
+
+`Those` as a demonstrative pronoun refers to specific items previously mentioned or understood from the context.

+
+This option, while somewhat accurate, doesn't fully capture the metaphor of filling and emptying versus locked boxes that Sophia used.
+
+---
+
+Variables can store multiple types of data at once, whereas constants can only store one type.
+
+### --feedback--
+
+This statement is misleading because it focuses on the types of data rather than how the data can be altered or remains fixed, which is the main point of Sophia’s explanation.
+
+---
+
+Variables act as containers that can be filled and emptied, while constants act as locked boxes that keep unchanged contents.
+
+---
+
+Variables are always changing, and constants are never used more than once.
+
+### --feedback--
+
+This option is incorrect as it suggests constants are never used more than once, which is not true. They are used repeatedly but their values do not change.

+
+The connector `so` is used to introduce a result or effect related to what has been said. It often shows a cause-and-effect relationship between two parts of a sentence.
+
+For example, `It was raining, so we canceled the picnic.` This shows that the picnic was canceled because of the rain.
+
+# --question--
+
+## --text--
+
+Which sentence is using `so` correctly?
+
+## --answers--
+
+`I was hungry so I am eating.`
+
+### --feedback--
+
+This sentence almost uses `so` correctly, but the tense in the second part should match the first. It would be correct to say: `I was hungry, so I ate.`
+
+---
+
+`She is late to work, so she misses the meeting.`
+
+### --feedback--
+
+The use of `so` suggests a consequence, but the tenses are mismatched. It should be: `She is late to work, so she will miss the meeting.`
+
+---
+
+`It started raining, so we took shelter.`
+
+---
+
+`He likes to read books, so he buys a lamp.`
+
+### --feedback--
+
+This sentence does not correctly use `so` because buying a lamp is not a direct result of liking to read books. A better use might be: `He likes to read at night, so he bought a lamp.`

+
+`Can` is used to show that something is possible or someone is capable of doing something, while `can't` is a contraction of `cannot`, indicating that something is impossible or someone is incapable of doing something. Both words should be followed by the base form of verbs.
+
+Examples:
+
+`I can swim.` (showing ability)
+
+`I can't swim.` (showing inability or lack of ability)

+
+Which sentence is using `can` or `can't` correctly?
+
+## --answers--
+
+`I can to play the guitar.`
+
+### --feedback--
+
+This sentence is incorrect because `to` should not be used with `can`. The correct sentence would be: `I can play the guitar.`

+
+`She can't see without her glasses.`
+
+---
+
+`We can goes to the park tomorrow.`

+
+### --feedback--
+
+`Can` should be followed by the base form of the verb without `ing`. The correct sentence should be: `He can drive at night.`

+Please answer the question below.
+
+# --question--
+
+## --text--
+
+Based on Tom's explanation, which scenario best illustrates the difference between variables and constants in a practical situation?
+
+## --answers--
+
+Variables are like the volume of a radio, which you can adjust anytime, whereas constants are like a sealed CD, whose songs cannot be altered.
+
+---
+
+Variables and constants both need regular updates to stay effective.
+
+### --feedback--
+
+This option is incorrect because constants do not change or need updates; they remain the same, unlike variables which can be updated.
+
+---
+
+You can pause or play music on a radio, just as you can switch variables and constants on and off.
+
+### --feedback--
+
+This isn't right because constants, unlike variables, cannot be 'switched off' or altered; they are permanent once set.
+
+---
+
+Tom can only use constants during certain times of the day, while variables can be used anytime.
+
+### --feedback--
+
+This statement is misleading as it suggests that the use of constants is time-restricted, which isn't true. Constants, like variables, do not have usage restrictions based on time but are defined by their unchangeable nature.
