2⟩ Do you know what is Luman?
Lumen is a new project from Laravel creator Taylor Otwell. It's a "micro-framework", meaning it's a smaller, faster, leaner version of a full web application framework. It competes other popular micro-frameworks, Slim and Silex.
3⟩ Do you know what is HTTP middleware?
Middleware provide a convenient mechanism for filtering HTTP requests entering your application. For example, Laravel includes a middleware that verifies the user of your application is authenticated. If the user is not authenticated, the middleware will redirect the user to the login screen. However, if the user is authenticated, the middleware will allow the request to proceed further into the application.
Of course, additional middleware can be written to perform a variety of tasks besides authentication. A CORS middleware might be responsible for adding the proper headers to all responses leaving your application. A logging middleware might log all incoming requests to your application.
There are several middleware included in the Laravel framework, including middleware for authentication and CSRF protection. All of these middleware are located in the app/Http/Middleware directory.

9⟩ Tell me why Doesn't Laravel Use Semantic Versioning?
On one hand, all optional components of Laravel (Cashier, Dusk, Valet, Socialite, etc.) do use semantic versioning. However, the Laravel framework itself does not. The reason for this is because semantic versioning is a "reductionist" way of determining if two pieces of code are compatible. Even when using semantic versioning, you still must install the upgraded package and run your automated test suite to know if anything is actually incompatible with your code base.
10⟩ Tell us can laravel be hacked?
Answers to this question is NO.Laravel application’s are 100% secure (depends what you mean by “secure” as well), in terms of things you can do to prevent unwanted data/changes done without the user knowing.

All Laravel routes are defined in your route files, which are located in the routes directory. These files are automatically loaded by the framework. The routes/web.php file defines routes that are for your web interface. These routes are assigned the web middleware group, which provides features like session state and CSRF protection.
