5. Great Bosses Are Consistent
Your team members want to know what to expect from you. They definitely don’t want to ride an emotional rollercoaster every time they step into the office. 

In fact, The Academy of Management Journal published a study in 2016 that found that inconsistent treatment caused employees to experience more psychological stress than being treated consistently unfairly.

6. Great Bosses Stay Positive
Positivity is a key leadership trait. As we all know, things don't always go to plan in the business world. When challenges present themselves, your positive attitude will help keep your staff confident and focused on the tasks at hand.

Always look for the silver lining in each and every situation. Not only will this create a more enjoyable working environment for your team, but it will also teach them to think positively as well, which, in turn, will allow them to produce their best work on a consistent basis.
Response: Great bosses are both consistent and positive. Employees need to know what to expect from their boss and when something goes wrong, a great boss knows to remain positive. Consistency and positivity create an enjoyable working environment for your team. 

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

Photosynthesis is the process by which plants convert light energy into chemical energy. This process produces glucose, which plants use as food, and oxygen, which they release into the atmosphere. It is essential for the growth of plants and the production of oxygen that other living beings need to survive.
