The evaluation is brief and shows a little evidence of critical thinking, but certainly needs to develop more.

Good reference.

The summary has a need to be better organised under one topic. All the points seem generally related but separate. Sentences are usually short and sometimes too short. A few reporting verbs are used but more problems are created by inaccuracy.

Evaluation

A well structured and more readable section, showing critical approaches and comparison of source topics.

There is a citation, which does not seem to relate to the 2 articles. More likely is that it is a mistake and the citation should read :                              ( Viswanathan,et al.,2009). 

An informed and well organised summary which could use more reporting verbs. You see past the general detail of the social media platforms and understand our relationship with news.

Evaluation

There is a bias toward the technological developed countries. Developed countries are forgotten. You are correct to say that we have to solve the problem ourselves.

Reliability
The reliability also rests with the author and the background of their work. 

An acceptable summary which focuses on the statistics of women in the top company jobs. some good writing and vocabulary used, like reporting verbs.

Evaluation

An acceptable evaluation which identifies the rest of women in society as equal partners to the top boardroom women!

Reliability

You make a good point of the Guardian but the Cranfield School should also be mentioned.
