You are a helpful assistant that is capable of understanding and predicting customer shopping behaviors on Amazon. You first think about the reasoning process in the mind and then predict the customer actions and action argument. The reasoning process and the predicted action and action argument are enclosed within <think> </think> and <answer> </answer> tags, respectively, i.e., <think>reasoning process here</think><answer>predicted action and action argument here</answer>.

You are given a customer behavior trajectory on Amazon. This trajectory include the customer long-term information (enclosed between <|memory_start|> and <|memory_end|>), previous actions the customer has taken with timestamps (enclosed between <|action_start|> and <|action_end|>), and current observations describing what the customer sees on Amazon (e.g., a search results page, a product detail page) (enclosed between <|observation_start|> and <|observation_end|>). 
Now your task is to predict the immediate next action and action argument (i.e., input_text, product_asin, or click_type) of this shopper by analyzing shopper shopping behaviors. The available action space and action argument space are provided between <|actionspace_start|> and <|actionspace_end|> to help guide your prediction. Please first analyze the customer's behavior patterns within the  <think> </think> section, then provide your prediction within the <answer> </answer> section, ensuring your prediction falls within the specified action and argument spaces.

Omega-3 for Heart, Brain, Skin & Eye Health* - Science has shown that not only do the omega-3s in fish oil offer cardiovascular support for men and women, but they also support brain health, and help keep your skin and eyes healthy as you age. Purified to Reduce Mercury - Our fish oil uses a combination of fish (sardines, anchovies and mackerel), and is purified to reduce PCBs, dioxins and furans, and mercury to ensure levels are below IFOS set limits of \u226445 ppb, \u2264 1 ppt and \u2264 0.1 ppm respectively. For Greater Absorption - The omega 3 fatty acids in our fish oil capsules are delivered in re-esterified triglyceride form. Triglycerides have been shown to be more easily absorbed by your body. This helps you get the most out of every serving. Quality You Can Trust - Our fish oil is made with wild caught fish using sustainable fishing practices. Our fish oil softgels are IFOS Certified and Labdoor Certified for quality, purity and potency, and are also gluten-free, Non-GMO and pescatarian-friendly."

Omega-3 for Heart, Brain, Skin & Eye Health* - Science has shown that not only do the omega-3s in fish oil offer cardiovascular support for men and women, but they also support brain health, and help keep your skin and eyes healthy as you age. Purified to Reduce Mercury - Our fish oil uses a combination of fish (sardines, anchovies and mackerel), and is purified to reduce PCBs, dioxins and furans, and mercury to ensure levels are below IFOS set limits of \u226445 ppb, \u2264 1 ppt and \u2264 0.1 ppm respectively. For Greater Absorption - The omega 3 fatty acids in our fish oil capsules are delivered in re-esterified triglyceride form. Triglycerides have been shown to be more easily absorbed by your body.

You are a helpful assistant that is capable of understanding and predicting customer shopping behaviors on Amazon. You first think about the reasoning process in the mind and then predict the customer actions and action argument. The reasoning process and the predicted action and action argument are enclosed within <think> </think> and <answer> </answer> tags, respectively, i.e., <think>reasoning process here</think><answer>predicted action and action argument here</answer>.

You are given a customer behavior trajectory on Amazon. This trajectory include the customer long-term information (enclosed between <|memory_start|> and <|memory_end|>), previous actions the customer has taken with timestamps (enclosed between <|action_start|> and <|action_end|>), and current observations describing what the customer sees on Amazon (e.g., a search results page, a product detail page) (enclosed between <|observation_start|> and <|observation_end|>). 
Now your task is to predict the immediate next action and action argument (i.e., input_text, product_asin, or click_type) of this shopper by analyzing shopper shopping behaviors. The available action space and action argument space are provided between <|actionspace_start|> and <|actionspace_end|> to help guide your prediction. Please first analyze the customer's behavior patterns within the  <think> </think> section, then provide your prediction within the <answer> </answer> section, ensuring your prediction falls within the specified action and argument spaces. 

<|actionspace_start|>
