Writing Feedback / GRE essay-As people rely more and more on technology to solve problems, [3]

You have a great start and some very interesting information! Generally, the order in which you present your information is relatively good, although the presentation of human innovations is a bit choppy at times. My primary suggestion is that you introduce your main points in separate paragraphs to very clearly show that you have included the requested information (e.g. your agreement/disagreement with the statement; arguments supporting your opinion). Your examples of human innovation are all relevant, but you might want to select just a few examples and provide a little more information about each one. Then you can tie them to your reasoning for coming to your conclusion about the title statement.

Also, you touch on cognitive ability and brain functioning, which is great to support your opinion. Add more! Those points directly relate to your position and will make your argument stronger. Connect your examples to the ways the statement might hold true or be proven unlikely.

For now, I think additional information will help you tie the innovations you cite to your conclusion. It should help you organize the essay more easily so that you have a concise introduction and conclusion, with your supporting information in between.

Grammar and punctuation is pretty good and can be corrected relatively easily once you add information and get your essay organized the way you want it to. Keep doing what you're doing!

Writing Feedback / World population growth will be at the highest point in the near future; IELTS [3]

The topic is timely and you have a good bit of information to get started. Rather than beginning the essay reporting data, however, you might introduce your main theme and the points you will discuss in a more general, but concise, way. Your second paragraph expresses your topic more generally and could be used as part of the introductory paragraph. For example:

Population growth rates vary widely across continents, countries and regions. Although the world's overall population growth rate has been declining since the 1960's, the growth rate in developing countries has increased dramatically.

Once you clarify your topic and purpose in the introduction, you can present your data in the paragraphs to follow. Try to present your data very clearly and group major themes together. For example:

The world's population grew slowly but steadily from about 1800 to the 1940's. In the 60 years to follow, though, the world experienced a substantial increase in the rate of population growth; an increase that is projected to continue until 2040. Population growth rates are then projected to begin to decline.

Generally, you have a good start and some good information. Adding an introductory paragraph and writing about your data very clearly should get you moving.
