Summarize the following:
If a conversation can benefit by your participation, jump in. Healthy exchange of ideas is essential to becoming a more understanding person. There's usually an opportunity to learn from deep, emotionally-invested discourse, and an opportunity to impart some wisdom of your own. Preface opinionated comments with phrases like "I think..." or "it's my belief that" Be aware of how you present yourself in discussions on politics, religion and ethical issues, as these can easily breed conflict. Get active in making plans or coming to decisions. Explain your line of thinking and make it clear what your preferences are. By holding your tongue, you forfeit your say-so in the decisions that get made, even when they affect you. An action as small as vetoing an option for where to eat lunch can make you feel more empowered to speak. If you're unsure whether a particular idea will be accepted, make it sound like you're just brainstorming. Try something like "Do you think it would work better if we..." or "What if instead of going to the theater, we curl up and watch a movie on the couch?" Failure to speak up can be misinterpreted as permissiveness or indifference. If you're opposed to something, say so. Take an outspoken stance on objectionable issues, behaviors and beliefs in no uncertain terms. Otherwise, you're as much to blame for circumstances as the person who has created them. A scornful glance will never have the same effect as forcefully asking "What makes you think it's acceptable to behave that way?" You can't change the way things are until you first point out what's wrong with them. Be polite, cool-headed and willing to listen even (maybe especially) when an ordinary discussion turns into an argument. Do your best to always encourage respectful and open-minded communication. The way you carry yourself in conversation should serve set a positive example. Knowing when it's best to withhold your opinion or stifle the urge to voice your thoughts is just as important as knowing when to speak proudly. Resist the temptation to stoop to using insults in the midst of a heated argument. "I'm sorry, but I disagree" gets the same point across, but without the hostility. It's much more likely that the person you're talking to will listen and take you seriously if you're able to keep a cool head. Think twice before saying anything that you know might offend or be taken the wrong way.

summary: Contribute to enlightening discussions. Involve yourself in the decision-making process. Don't let silence be mistaken for approval. Keep it civil.

Summarize the following:
Cut each onion in half. Place on the baking sheet or dish. Sprinkle salt and pepper over the onions. Roast for 20-30 minutes. They are ready when golden brown and tender. Before serving and while still hot, drizzle with a generous serve of balsamic vinegar.

summary: Preheat the oven to 425F/220C. Peel the onions. Brush the onions in oil. Place in the oven. Remove from the oven.

Summarize the following:
Installing a shorter lever arm is the best way to adapt a racer for speed. However, if the lever is too short, it will spin out. There is no precise formula for how long the lever should be. Experiment to see how short you can get the lever while maintaining control of the car. Longer lever arms will extend the time in which the axle is pulled, making it travel longer distances before the car reaches maximum speed. As a result, it will go slower, but move further. When you increase the size of the wheel, the amount of torque necessary to begin a rotation increases as well. A smaller wheel is easier to turn. So you should make sure that your driving (front) wheel is as small as possible. A good standard is approximately 3 inches (7.6cm) in diameter. Use materials that are as lightweight as possible. A larger wheel means more rotational inertia, which keeps the wheel moving once it gets going, but reduces acceleration. A smaller wheel is a trade-off between distance and speed. The overall distance traveled will decrease as you reduce the size of the driving wheel. Experiment to determine what the most functional design is. The greater the ratio of the diameter of the axle to the wheel, the less force will be required to accelerate the car. In other words, you should match a larger axle with a smaller wheel to increase acceleration. Conversely, a mousetrap racer built for distance should have a smaller axle and a larger driving wheel. One way to adapt the size of the axle is to wrap tape around the center of the axle, where it does not come into contact with the frame. This added weight will increase the torque of the axle. Experiment to find the correct amount of torque by adding and removing layers of tape. For the wheel to pick up speed it needs to create pressure against the ground. For the wheel, use a material with a rough texture around the outside to give the wheel traction. Alternatively, cut something that has a rough surface such as a rubber balloon. Glue strips of this material to the outside of the wheel to give it traction. There are so many variables involved in the physics of a mousetrap racer that even similarly built cars operate differently. The only way to perfect your model is to experiment with small variations in design to determine what works best. Study mousetrap racers that have won competitions in the past. Learn from designs that you know work.
summary: Shorten the lever arm. Find smaller wheels. Increase the size of the axle. Increase traction. Keep on trying.
