Final answer:
A 'brain child' is an invention, indicating that you invented it. Examples of everyday gadgets like smartphones, laptops, and smartwatches illustrate the profound effect inventions have on daily life and the world at large.
Step-by-step explanation:
If a gadget is referred to as your "brain child," it means that you invented it. 'Brain child' is a term used to describe an idea or invention that is the product of one's creative effort and imagination. It indicates original creation rather than imitation. Therefore, the answer is 1) Invent it.
To understand how inventions affect lives, consider three electronic devices that one might use every day:
- Smartphone: used for communication, accessing the internet, and managing daily tasks. It has revolutionized how we connect with others and access information.
- Laptop: used for work, education, and entertainment. It has made information and services more accessible and has transformed how we learn and perform professional tasks.
- Smartwatch: used for health tracking and notifications. It has improved health awareness and convenience in staying connected.
If these devices had not been invented, their absence would significantly affect productivity, global communication, entertainment options, and health management, demonstrating the immense impact of technological innovation.
