answer：First, I need to determine the walking speeds of both Mark and Chris. The problem states that Chris walks at 3 miles per hour, and Mark travels at the same speed, so Mark's speed is also 3 mph.Next, I'll calculate the time it takes for Chris to reach school. Since the distance from their house to the school is 9 miles and Chris walks at 3 mph, the time taken is 9 miles divided by 3 mph, which equals 3 hours.Now, I'll figure out Mark's journey. Mark walks 3 miles towards school at 3 mph, which takes 1 hour. After walking 3 miles, he realizes he forgot his lunch and has to turn around and walk back home. The return trip is also 3 miles at 3 mph, taking another hour. Therefore, Mark spends a total of 2 hours walking.Finally, to find out how much longer Mark spends walking than Chris, I'll subtract Mark's total walking time from Chris's time: 3 hours minus 2 hours equals 1 hour. So, Mark spends 1 hour longer walking than Chris.

answer：Okay, so I need to figure out whether this product review is flattering or unflattering. Let me read through the review again carefully.The title is "Not what I had hoped," which already gives a negative impression. The reviewer starts by saying they found the product difficult to use and not very helpful as a practicing tool. That's a clear criticism. They mention that the flash animation was too elaborate and caused their computer to slow down, making the screen not keep up with their performance. They acknowledge that this might be their computer's fault, but still, it's a negative point about the product's performance.Next, they express frustration with the grading system, which focused on holding notes exactly rather than allowing for inflections and vibrato. This suggests that the product didn't meet their expectations in terms of how it assesses performance. They conclude by saying it was a good idea in theory but not worth the price they paid, which is a strong negative statement about the product's value.Putting it all together, the review is mostly negative. The reviewer had several issues with usability, performance, and the grading system, and they felt it wasn't worth the money. Even though they mention it's a good idea, the overall tone is critical and disappointed.

answer：Okay, so I'm trying to figure out whether the hypothesis "The tinted sunglasses were a birthday gift from a friend." is true based on the given premise. The premise is: "A woman with a tattoo sits with a pair of yellow tinted sunglasses on her multicolored hair." First, I'll break down the premise. It describes a woman who has a tattoo and is wearing yellow tinted sunglasses on her multicolored hair. That's all the information given. Now, the hypothesis is about the origin of the sunglasses—specifically, that they were a birthday gift from a friend.I need to see if the premise provides any information that supports or contradicts this hypothesis. The premise mentions the woman's appearance: she has a tattoo, multicolored hair, and is wearing yellow tinted sunglasses. However, it doesn't say anything about where she got the sunglasses, who gave them to her, or any context about birthdays or friends.So, the premise is purely descriptive about her appearance at a particular moment. It doesn't give any clues about the reason she has the sunglasses or who gave them to her. Therefore, there's no information in the premise that would allow us to conclude whether the sunglasses were a birthday gift from a friend or not.I might be tempted to think that maybe the sunglasses are a gift because they're a specific color, but that's just an assumption. The premise doesn't provide any evidence for that. Without additional information, we can't make that connection.So, in conclusion, based solely on the premise given, we don't have enough information to determine the origin of the sunglasses. It's possible that they were a gift, but it's also possible they were bought by her, or perhaps they're just her own property. There's no way to tell from the premise alone.

answer：Okay, so I need to translate the English sentence "Special Fund estimated resource requirements 29" into Arabic. Let me break this down step by step.First, I'll look at each part of the sentence to understand what each word means and how they fit together. The sentence has four main components: "Special Fund," "estimated," "resource requirements," and the number "29."Starting with "Special Fund." In Arabic, "Special" can be translated as "خاص" (khās) and "Fund" is "фонд" (fond), but in Arabic script, it's written as "фонд" which is transliterated as "fond." So together, it would be "ال фонд الخاص" (al-fond al-khās). Wait, actually, in Arabic, the definite article "ال" comes before the noun, so it should be "الфонد الخاص" (al-fond al-khās).Next is "estimated." This is a verb in the past tense, meaning something was calculated or approximated. The Arabic word for "estimated" is "قدّر" (qaddara), but in the past tense, it's "قدّر" (qaddara). However, since it's describing the fund, it might be better to use the adjective form. The past participle of "قدّر" is "مقدور" (maqḍūr), but that might not fit perfectly here. Alternatively, "estimated" can be translated as "تقدير" (takwīd), but that's more of a noun. Maybe "تقدير" as an adjective would be "مقدر" (maqdir). Hmm, perhaps it's better to use the verb in a different form or structure the sentence differently.Moving on to "resource requirements." "Resource" in Arabic is "مورد" (mawrid), and "requirements" is "متطلبات" (mtatlubāt). So together, it would be "متطلبات الموارد" (mtatlubāt al-mawārid).Finally, the number "29" is "تسعة وعشرون" (tisʿa wa-ʿishrūn) in Arabic.Putting it all together, I need to structure the sentence correctly. In English, it's "Special Fund estimated resource requirements 29." In Arabic, the structure might be "قدّر фонд الخاص متطلبات الموارد تسعة وعشرون." But I'm not sure if that's the most natural way to phrase it.Wait, maybe I should start with the verb. So "قدّر" (qaddara) meaning "estimated," followed by the subject "الфонد الخاص" (al-fond al-khās), then the object "متطلبات الموارد" (mtatlubāt al-mawārid), and finally the number "تسعة وعشرون" (tisʿa wa-ʿishrūn). So the full sentence would be "قدّر фонд الخاص متطلبات الموارد تسعة وعشرون."But I'm a bit unsure about the word order. In Arabic, the typical structure is verb-subject-object, so that seems correct. However, I'm not entirely confident about the translation of "estimated." Maybe using "تقدير" as a noun would make more sense, like "تقدير фонд الخاص لمتطلبات الموارد هو تسعة وعشرون." That would translate to "The estimation of the Special Fund for resource requirements is twenty-nine."Alternatively, using "قدّر" as a verb might be more direct. I think both translations are possible, but the second one using "تقدير" might be clearer. So the sentence would be "تقدير Fond الخاص لمتطلبات الموارد هو تسعة وعشرون."Wait, but "Fond" is written as "фонд" in the original, which is the Russian word for "Fund." In Arabic, it's still "фонд" but pronounced as "fond." So I should keep it as "الфонد" (al-fond) to maintain consistency.Putting it all together, the sentence would be "تقدير фонد الخاص لمتطلبات الموارد هو تسعة وعشرون."I think that makes sense. Let me double-check each part:- "تقدير" (takwīd) = estimation- "фонد" (fond) = fund- "الخاص" (al-khās) = special- "ل" (li) = for- "متطلبات" (mtatlubāt) = requirements- "الموارد" (al-mawārid) = resources- "هو" (huwa) = is- "تسعة وعشرون" (tisʿa wa-ʿishrūn) = twenty-nineSo the full sentence is "تقدير фонد الخاص لمتطلبات الموارد هو تسعة وعشرون."I think that's a correct translation. Alternatively, if I use the verb "قدّر" (qaddara), it would be "قدّر фонد الخاص متطلبات الموارد تسعة وعشرون," which also makes sense but might be less clear in meaning.I'll go with the first version using "تقدير" as it seems more precise.

answer：Okay, so I have this question about when Fort Sill was founded. The passage mentions that Danford served as an artillery instructor at Fort Sill in July 1917. But the link information says that the site of Fort Sill was staked out on January 8, 1869. I need to figure out which one is the correct founding year.First, I should understand what "founded" means. Typically, a fort is considered founded when it's established or when construction begins. The link information states that the site was staked out in 1869, which likely marks the beginning of its establishment. On the other hand, Danford's service in 1917 is much later and probably refers to a time when Fort Sill was already operational.So, the founding year would be when the site was initially marked, which is 1869. The 1917 date is just a later event at the fort, not its founding.

answer：Okay, so I have this task where I need to take a list of integers and letters, and then create a new list by dropping one item each time. The output should be a list of all these possible new lists. Let me think about how to approach this.First, the input given is ['H', '1', 'J']. I need to drop each element one by one and create a new list each time. So, for each element in the list, I'll remove it and see what the resulting list looks like.Let me start by identifying the elements. The list has three elements: index 0 is 'H', index 1 is '1', and index 2 is 'J'. So, for the first step, I'll drop the first element, 'H'. That leaves me with ['1', 'J']. That's one possible list.Next, I'll drop the second element, which is '1'. Removing that, the list becomes ['H', 'J']. That's the second possible list.Then, I'll drop the third element, 'J'. Removing that, the list is ['H', '1']. That's the third possible list.So, putting all these together, the output should be a list containing these three lists. Each inner list is the original list minus one element, each time a different one.Wait, let me make sure I'm not missing anything. The task says to drop one item each time, so each new list should have one less element than the original. Since the original has three elements, each new list should have two elements. And since there are three elements, there should be three new lists. That makes sense.I think I've covered all possibilities. So, the final output should be a list with three inner lists: ['1', 'J'], ['H', 'J'], and ['H', '1'].
