جلسة الأسئلة والأجوبة في برنامج المؤتمر.

Not really. By itself, it is most naturally a noun phrase or heading, not a full sentence with a verb.

Arabic often uses phrases like this for:

• schedule items
• titles
• labels
• section headings

So here it works like Q&A session in the conference program or The Q&A session in the conference program.

If you wanted a full sentence, you could say something like:

هذه جلسة الأسئلة والأجوبة في برنامج المؤتمر
= This is the Q&A session in the conference program.

It uses an iḍāfa construction, often called a genitive/possessive construction.

The basic structure is:

• جلسة = session
• الأسئلة والأجوبة = the questions and answers

So literally it is something like:

session of the questions and answers

In more natural English, that becomes:

Q&A session or question-and-answer session

Arabic usually puts the main noun first and then the thing attached to it. So where English often uses of, Arabic often uses iḍāfa instead.

Because جلسة is the first part of an iḍāfa, and the first noun in an iḍāfa normally does not take الـ.

So:

• جلسة الأسئلة والأجوبة = the session of the questions and answers / the Q&A session

Even without الـ on جلسة, the whole phrase can still be definite because the second part is definite.

This is a very common Arabic pattern:

• كتاب الطالب = the student’s book
• برنامج المؤتمر = the conference program
• جلسة الأسئلة والأجوبة = the Q&A session

They are plural because the phrase refers to a session involving multiple questions and answers.

This is very natural Arabic:

• الأسئلة = the questions
• الأجوبة = the answers

Yes, Arabic can also use singular forms in a more generic expression, such as:

جلسة سؤال وجواب
= a question-and-answer session

That version is also common. The plural version جلسة الأسئلة والأجوبة sounds a bit more explicit and formal.

They are broken plurals, not regular sound plurals.

• سؤال = question
  plural: أسئلة
• جواب = answer
  plural: أجوبة

A broken plural means the inside pattern of the word changes, rather than just adding a regular ending.

That is extremely common in Arabic, so learners need to memorize many plurals individually.

No. Another very common plural is إجابات.

So both of these can mean answers:

• أجوبة
• إجابات

In this exact pairing, الأسئلة والأجوبة is a well-established and very natural phrase, especially in formal Arabic.
الأسئلة والإجابات is also understandable and used, but الأسئلة والأجوبة often sounds a bit more fixed or traditional.

Literally, it means in the conference program.

Here:

• في = in
• برنامج = program
• المؤتمر = the conference

So برنامج المؤتمر is another iḍāfa:

• program of the conference
• more naturally: the conference program

Depending on context, English might also say:

• in the conference schedule
• on the conference agenda
• as part of the conference program

Because و meaning and is a clitic in Arabic. It is written attached directly to the following word.

So:

• و + الأجوبة becomes
• والأجوبة

This is normal Arabic spelling.

The same happens with many short particles, such as:

• والكتاب = and the book
• بالمؤتمر = in/at the conference
• للطلاب = for the students

A practical pronunciation is:

jalsat al-asʾila wa-l-ajwiba fī barnāmaj al-muʾtamar

A few useful points:

• جلسة ends in ة.
  In pause by itself, that ending usually sounds like -a.
  But when connected in a construction like this, it is pronounced with t.

• أسئلة has a hamza in the middle: asʾila.
  There is a small glottal stop between s and i.

• مؤتمر also has a hamza: muʾtamar.

So the phrase has two important hamzas to notice:

• أسئلة
• مؤتمر

In fully inflected MSA, the internal grammar would look like this:

جَلْسَةُ الأَسْئِلَةِ وَالأَجْوِبَةِ فِي بَرْنَامَجِ المُؤْتَمَرِ

If this whole phrase is standing as a title or heading, people often do not pronounce the endings in normal reading. But grammatically:

• الأسئلةِ is genitive because it is part of the iḍāfa after جلسة
• الأجوبةِ is also genitive because it is joined to الأسئلة
• برنامجِ is genitive because it comes after في
• المؤتمرِ is genitive because it is the second part of the iḍāfa برنامج المؤتمر

The first word جلسة changes depending on its role in the larger sentence:

• جلسةُ if nominative
• جلسةَ if accusative
• جلسةِ if genitive

So in a heading, you may simply see جلسة الأسئلة والأجوبة في برنامج المؤتمر without vowels, but formal grammar still explains how the phrase is built.
