answer:Let's think step by step. When the tap is open, it fills the tub with 12 liters per minute, but 1 liter escapes through the cap, so the net gain is 11 liters per minute during the open phase. When the tap is closed, no water is added, but 1 liter escapes, so the net loss is 1 liter per minute during the closed phase. The tub needs to be filled with 120 liters. Since Robi Ney alternates between open and closed phases, every 2 minutes there is a net gain of 11 - 1 = 10 liters. To calculate the number of 2-minute cycles required to reach 120 liters, we can divide 120 by 10: 120 / 10 = 12 cycles. Each cycle takes 2 minutes, so 12 cycles will take 12 * 2 = 24 minutes. However, the tub will be filled within the last open phase, so we don't need the last 1-minute closed phase. Therefore, the total time needed to fill the tub is 24 - 1 = 23 minutes. The answer is: 23.

answer:Step 1: Analyze the first statement - "People are looking at papers hanging on a wall." This statement tells us that there are multiple people looking at papers on a wall. Step 2: Analyze the second statement - "A man examining some papers." This statement tells us that there is a man who is examining some papers. Step 3: Compare the two statements. The first statement involves multiple people, while the second statement involves a single man. Step 4: Determine if the second statement can be inferred from the first statement. Since the first statement tells us that there are multiple people looking at papers, it is possible that one of those people is a man examining the papers. However, the first statement does not specifically mention a man or the act of examining the papers. Step 5: Provide the final answer. Based on the comparison of the two statements, the answer is: it is not possible to tell.

answer:Step 1: Analyze the given sentence The sentence provided is "People are crossing the signal." Step 2: Identify the information available The information we have is that people are crossing a signal, which could imply they are crossing a street or intersection where there is a traffic signal. Step 3: Determine if the information is enough to conclude that they are running late From the information provided, we cannot determine their reasons for crossing the signal. It could be that they are running late, but it could also be that they are simply crossing the street as a part of their normal routine. Step 4: Choose the appropriate option Based on the available information, it is not possible to tell if they are running late. Answer: it is not possible to tell

answer:Step 1: Identify the key information in the sentence. In this case, we have a man, a black sweater and cap, looking at a paper, and drinking out of a wineglass. Step 2: Determine if the information supports the statement "A man is drinking some wine." We know the man is drinking out of a wineglass, which is typically used for drinking wine. Step 3: Consider possible alternatives. It's possible that the man is drinking something other than wine from the wineglass, such as water or juice. Step 4: Compare the given information with the alternatives. We do not have enough information to confirm that the man is specifically drinking wine, as he could be drinking another beverage from the wineglass. Based on these steps, the answer is: it is not possible to tell.
