Band 4+: You are currently renting an apartment, and you've noticed a recurring problem with the building's water supply. Write a letter to your landlord. - Describe the water supply problem and how long it has been occurring - Explain how this problem is affecting you - Suggest a solution to resolve the issue and request a timeline for repair

The letter addresses the task requirements by describing the water supply problem, explaining its impact, and suggesting a solution with a timeline. However, the tone could be more formal and the explanations could be more detailed to enhance the response. For example, elaborating on the specific daily activities affected and providing a more precise description of the problem's impact would strengthen the letter. Also, ensure correct spelling and grammar throughout the letter. The letter falls short of the required 150 words.

The letter's organization is somewhat clear, but could benefit from more distinct paragraphing to separate the description of the problem, its impact, and the suggested solution. Transitions between ideas could also be smoother to improve the flow.

The vocabulary used is basic and lacks the precision needed to effectively convey the issues. Consider using more descriptive words to explain the problem and its impact. For example, instead of 'it stank,' you could describe the specific odor. Boost vocabulary complexity to elevate the overall score.

There are several grammatical errors that affect the clarity of the letter. Pay attention to verb tense consistency, correct article usage (a/an/the), and sentence structure. Proofreading carefully before submitting would help catch these errors.
