So I'll start with the first one, and I'll let Sherry comment on the Q4. Look, in terms of customer activity, I can give you three activity, I can give you three dimensions. The service dimension, the consumables consumption dimension, and access to our - for our sales teams. Let's start with consumables. I mean, we've seen the experimentation go up in the labs and consumables growth is mid-to-high single digits and went into the double digits for China. So across all regions, especially in pharma, we start to see activity in the labs, as measured by our consumables revenue. As far as our service - access for our service teams is concerned, we saw some return to normal, especially in China and in Europe and increasing steadily in the U.S., but I would not conflate that with pre-pandemic levels, right. So our service engineers have a very different experience these days and they visit customers apart from having PPE and doing testing before they go to many customers. The duration of the visits are much shorter, as customers have them in, and they want them out after a certain specific period of time. So while the overall activity and access to labs for service engineers has increased, it is still not like it used to be prior to the pandemic. And then finally, from a direct sales perspective, our sales engineers, I would say, have 15% to 20% access, especially in the U.S. and in Western Europe versus what they used to pre-pandemic, and they're really leveraged webinars and a lot of virtual interaction. And many of them, in fact, I was with the sales team in the U.S. recently. And many of them say, look, we hope the customers are willing to engage in the same way, even post the pandemic because it's highly efficient and effective, it prevents unnecessary travel, then you don't need to. And of course, there is no substitute for face-to-face interaction when we're able to do it. Yet that said, there are some benefits that are coming out. So I hope that gives you more color on the access. For the Q4 question, I'll pass it on to Sherry.
