The problem of unemployment is emasculating our youth from making concrete innovations.

hindering
pressurizing
encouraging
weaken

The correct answer is: A. hindering

The word “emasculating” means to deprive of strength, vigor, or effectiveness. In this context, it is being used to describe how the problem of unemployment is preventing young people from making concrete innovations.

The other options are not as accurate. “Pressurizing” suggests that unemployment is putting young people under a lot of stress, but it does not necessarily mean that it is preventing them from innovating. “Encouraging” suggests that unemployment is motivating young people to innovate, but this is not the case. “Weaken” is similar to “emasculating,” but it does not convey the same sense of severity.

In conclusion, the correct answer is “A. hindering.”
