Mostly, yes. In 请回答这个问题, 请 makes the sentence sound like a polite request: Please answer this question.

A few useful notes:

• 请 often means please before a verb:
  • 请坐 = Please sit
  • 请看 = Please look
• It can also mean to invite in other contexts:
  • 我请你吃饭 = I’m treating you to a meal / I invite you to eat

In this sentence, it is clearly the please meaning.

Chinese often leaves out the subject when it is obvious from context. In a classroom or conversation, 请回答这个问题 naturally means:

• Please answer this question
• understood as Please, you answer this question

If you want to make you explicit, you can say:

• 请你回答这个问题

That is also very natural. The version without 你 is common and concise.

回答 is a verb meaning to answer or to reply.

It is made up of two characters:

• 回 = to return
• 答 = to answer

But in modern Mandarin, you should learn 回答 as a single verb. It can take an object directly:

• 回答问题 = answer a question / answer questions
• 回答这个问题 = answer this question

So in this sentence, 回答 is the main verb.

Because in Chinese, when a demonstrative like 这 (this) comes before a noun, it usually needs a measure word.

The pattern is:

• 这 + measure word + noun

So:

• 这 + 个 + 问题 = 这个问题 = this question

Here, 个 is the measure word. It is a very common general measure word.

For learners, it is best to remember:

• 这本书 = this book
• 这个人 = this person
• 这个问题 = this question

You may occasionally hear omissions in casual speech, but 这个问题 is the standard form to use.

Because 问题 is treated as a countable noun, and 个 is the most common general measure word in Mandarin.

So:

• 一个问题 = one question
• 两个问题 = two questions
• 这个问题 = this question
• 那个问题 = that question

Some nouns have special measure words, but 个 is the normal one here.

They are different parts of speech and have different meanings:

• 问 is usually a verb: to ask
• 问题 is a noun: question or problem

Examples:

• 我问你一个问题。 = I ask you a question.
• 请回答这个问题。 = Please answer this question.

So in your sentence, 问题 is the thing being answered.

It can mean both question and problem. The context tells you which meaning is intended.

Examples:

• 回答问题 = answer a question
• 这个问题很严重。 = This problem is serious

In 请回答这个问题, the meaning is clearly question, because 回答 (answer) goes naturally with a question.

It is fairly similar, but there are a couple of Chinese patterns to notice.

Sentence structure:

• 请 = please
• 回答 = answer
• 这个问题 = this question

So the order is:

• please + verb + object

That part is similar to English: Please answer this question.

But inside 这个问题, Chinese puts this before the noun with a measure word:

• 这 + 个 + 问题
• literally: this + measure word + question

So the whole sentence is straightforward, but the demonstrative + measure word + noun pattern is especially important.

It is polite enough in many situations, especially in classrooms, instructions, or formal speaking. But it can still sound a bit direct depending on tone and context.

Compare these:

• 请回答这个问题。 = polite request / instruction
• 请你回答这个问题。 = slightly more directed toward a specific person
• 请回答一下这个问题。 = a bit softer
• 麻烦你回答一下这个问题。 = even softer, more conversational

So the given sentence is not rude, but it is somewhat direct and is often used by teachers, interviewers, hosts, or exam instructions.

一下 often softens the tone. It can make a request sound lighter, less abrupt, and more natural in conversation.

Compare:

• 请回答这个问题。 = Please answer this question.
• 请回答一下这个问题。 = Please answer this question for a moment / Please go ahead and answer this question.

In English, we usually do not translate 一下 literally. Its job is often more about tone than meaning.

For learners, a good rule is:

• adding 一下 often makes requests sound softer and more natural

It is commonly written in pinyin as zhège, but in actual speech the second syllable is often light and unstressed.

So learners may hear something like:

• zhè ge

The key points are:

• 这 is fourth tone: zhè
• 个 here is often light in connected speech

So even if it is written zhège, you should not pronounce both syllables with equal emphasis in careful beginner-style speech forever. Native speech usually weakens 个 in this pattern.

Normally, 回答 is the more natural choice.

While 答 can appear in certain words and expressions, by itself it is not usually the most natural everyday verb here. Standard Mandarin strongly prefers:

• 回答这个问题

You may also hear:

• 答题 = answer questions on a test
• 作答 = answer formally, especially on exams

But for a normal sentence like Please answer this question, 请回答这个问题 is the safest and most natural phrasing.
