You are given access to make searches on the Internet. The format for making a search is:
1. After the user sends a message, you will decide whether to make a search. If you choose to make a search, you will output a single message, starting with the word <web_search>, followed by ONLY your web search query. After your search query, you must output the token </web_search> to denote the end of the search query. Keep your search query very concise.
2. The system will then append the web search results at the end of the user message, starting with the token <web_search_results>. Take note that the user CANNOT SEE the content after <web_search_results> - YOU should use these results appropriately to improve your response. Additionally, If the web search results are already present in the user's message, then you MUST NOT request another web search.

IMPORTANT! You should choose to search the web ONLY if ANY of the following circumstances are met:
1. User is asking about current events or something that requires real-time information (news, sports scores, 'latest' information, etc.)
2. User is asking about some term you are unfamiliar with (e.g. if it's a little-known term, if it's a person you don't know well, etc.)
3. User is asking about anything that involves numerical facts (e.g. distances between places, population count, sizes, date and time, etc.)
4. User explicitly asks you to search or provide links to references.
If the user's query does NOT require a web search, YOU MUST NEVER run one for no reason. However, you must not refuse to search the web if the user asks you to do so.
If you are highly unsure about whether to make a search (e.g. if the user's query is vague or if you think you are unfamiliar with the query to a certain extent), you may directly ask the user for clarification.

When using web search results, you are encouraged to cite references where appropriate, using inline links in standard markdown format.
You are also allowed to make use of web search results from previous messages, if they are STRONGLY RELEVANT to the current message.

When you are not running a web search, respond completely as per normal - there is NO NEED to mention that you're not searching. 
Remember that you MUST NOT make up any false information.
Assistant: Understood. I will strictly follow these instructions in this conversation.
User: should you build a watch on a solid surface like granite or a cloth surface like a mousepad
Assistant: Building a watch is best done on a solid surface like granite rather than a cloth surface like a mousepad. A solid surface provides a stable and even platform, reducing the risk of dropping or misplacing small components. Cloth surfaces can introduce risks such as static electricity, lint accumulation, and less stability, which might hinder precision work. Therefore, for watch assembly, a hard, flat surface is preferable.
User: silicone scrubber vs loofa
Assistant: Silicone scrubbers and loofahs each have their own advantages and disadvantages, depending on your needs:

**Silicone Scrubber:**
- **Durability:** Silicone scrubbers are typically more durable and long-lasting than loofahs. They can withstand higher temperatures and are less likely to harbor bacteria, as they dry quickly.
- **Easy to Clean:** They can be easily washed in the dishwasher.
- **Gentleness:** Silicone is gentle on the skin and suitable for sensitive skin types.

**Loofah:**
- **Natural Material:** Loofahs are natural, biodegradable, and can provide a more exfoliating experience due to their texture.
- **Softening Characteristics:** They tend to soften when wet, which can be more comfortable for some users.
- **Variety:** Loofahs come in various shapes and sizes for different uses, including for body scrubbing and washing dishes.

In summary, if you're looking for durability and easier maintenance, a silicone scrubber may be better suited for you. If you prefer a natural product with exfoliating properties, a loofah might be advantageous.
