answer:Safety's a top priority when you're out in the woods, especially when you're searching for a creature that's as elusive and potentially powerful as Bigfoot. I've had my share of close calls over the years, but I've learned to take precautions. First and foremost, I always let someone know where I'm going and when I plan to return. I've got a buddy in town, a fellow Sasquatch enthusiast, and we check in with each other every morning and night. If I don't check in, he knows to send someone looking for me. I also carry a satellite phone with me, just in case I get into a situation where I need to call for help. Cell phone reception's spotty out here, but the satellite phone will get a signal no matter where I am. I'm also careful about the terrain I navigate. I know these woods like the back of my hand, but I still take my time, especially when I'm walking in areas with steep drop-offs or fast-moving water. One wrong step, and you can end up in a world of trouble. I'm also mindful of the wildlife. I've had encounters with bears, mountain lions, and snakes, and I know how to react. I carry bear spray with me, and I know how to use it. I've also got a healthy respect for the forest's smaller creatures - I've had my share of run-ins with wasp nests and beehives, and I know how to avoid them. And then, of course, there's the weather. I've been caught in storms, and I know how quickly the weather can turn. I carry a waterproof jacket and pants with me, and I know how to start a fire even when it's wet. Hypothermia's a real concern out here, so I'm always prepared for the worst. As for Bigfoot itself, I'm not too worried. I believe the creature's generally shy and avoids humans. I've had a few close encounters, but I've never felt threatened. That being said, I do carry a camera with a motion sensor, so if I do encounter something, I'll have proof. I've also developed a bit of a sixth sense over the years. I can feel when something's off, when the energy in the forest changes. If I get that feeling, I trust my instincts and get out of there. It's better to err on the side of caution when you're dealing with the unknown. It's a combination of experience, preparation, and common sense that keeps me safe out here. And after all these years, I feel like I'm part of the forest itself. I know its rhythms, its moods, and its secrets. And I know that as long as I respect the forest and its creatures, I'll be okay.

answer:Here's how you could implement the `build_select_query` function: ```python import re def build_select_query(table_name, columns): if not isinstance(table_name, str): raise TypeError('table_name must be a string') if not isinstance(columns, list): raise TypeError('columns must be a list') for column in columns: if not isinstance(column, str): raise TypeError('columns must be a list of strings') def escape_special_characters(s): return re.sub(r'(['])', r'1', s) escaped_columns = ','.join(map(escape_special_characters, columns)) query = f'SELECT {escaped_columns} FROM {escape_special_characters(table_name)};' parameters = [] return query, parameters ``` The `build_select_query` function takes two arguments: `table_name`, a string representing the name of the table, and `columns`, a list of column names as strings. It then performs the following steps: - Validates the input arguments to ensure they are of the correct type. - Escapes special characters in the column names and table name using backslash escaping. - Builds the SELECT statement using the escaped column names and table name. - Returns a tuple of the query string and an empty list of parameters.

answer:To solve this, let's analyze the snail's progress. The snail effectively climbs 1 foot each day (3 feet up, 2 feet back). However, on the final day of climbing, the snail won't slip back because it will have already reached the top. The well is 20 feet deep. If the snail climbs 1 foot per day effectively, it would need 18 days to climb 18 feet (leaving 2 feet to climb on the last day). On the 18th day, it climbs 3 feet and reaches the top of the well but slips back 2 feet at night isn't a possibility because it's already out of the well. However, this approach only accounts for 18 feet. The snail climbs 3 feet on the 18th day. It needs to climb only 2 feet to get out of the well on the 18th day and since it climbs 3 feet in a day, it actually gets out of the well on the 18th day. Thus, the snail takes 18 days to reach the top of the well.

answer:On the 18th day, the snail climbs the final 2 feet it needs to reach the top and actually has 1 foot of climbing left over because it can climb 3 feet in a day. Since it reaches the top on that 18th day, it doesn't slip back because it has already escaped the well. So the correct answer is indeed 18 days.
