As an AI, I do not have the capability to directly access or browse external websites such as ted.com. However, I can provide you with guidance on how to find and assess a TED Talk yourself.

To find a speech by a professional speaker, go to the TED Talk website (ted.com) and use the search bar located at the top of the page. You can enter keywords related to the topic or speaker you are interested in, or you can browse through the different categories (like Technology, Science, or Education) to find a speech that appeals to you.

Once you have selected a TED Talk to listen to, pay attention to the speaker's structure and use of transitions. Look for how they organize their speech, whether they start with an attention-grabbing introduction, have a clear progression of ideas, and provide a concise conclusion. Also, observe how they use transitions like signal words, phrases, or visual aids to smoothly connect different parts of their speech or highlight critical points.

To help your understanding and retention of the speaker's message, consider the following factors:

1. Clarity: Assess if the speaker's structure and transitions help in delivering their ideas clearly. Do the transitions enable a smooth flow of information without causing confusion?

2. Coherence: Observe whether the speaker's structure and transitions effectively connect various parts of their speech, making it easier to follow the overall progression of ideas.

3. Engagement: Evaluate if the structure and transitions help maintain your interest and engagement throughout the talk. Do they help you stay focused on the speaker's message?

4. Retention: Reflect on whether the structure and transitions aid in retaining the key takeaways from the speech. Do they effectively reinforce important points and help you remember them after the talk?

After evaluating these aspects, you can assign a grade to the speaker's structure and transitions based on how well they contribute to your understanding and retention of the content.
