Internal Code: C_AI_DCFF_AGD Code: AGR3303

Agricultural Materials Presentation Assessment Answer

Assignment Task: QUESTION 1: The aim of this assignment question is to critically review the published literatures. To do this you will need to:

• Provide a coherent account of the issues raised in each of the research papers.
• Describe the links and correlations between the various theories investigated.
• Describe contradictions, ambiguities, weaknesses in the current knowledge outlined in the articles.

A concise and clear to the point presentation style is strongly encouraged in this assignment. The report should be well structured with appropriate uses of headings and sub-headings. The key points should be clearly emphasised and the extensive use of bullet points (dot points) is encouraged. There are a range of theories available to explain the mechanism of bruising in apples. These theories have been used in an attempt to predict the extent of bruising caused by different loading conditions. The papers by Holt and Schoorl (1977) (AGR3303 Selected Readings - Reading 5.1), and Siyami et al. (1988) (AGR3303 Selected Readings - Reading 5.2), investigate and test a number of these theories. Review these two papers.

• Briefly explain and summarise the different theories tested and the results obtained.
• Are the results described in the two papers compatible?
• Discuss which theory or mechanism appears to be most accurate.
• Compare the approaches in the two papers and consider which theory is more useful in practical terms (e.g. how would you use this knowledge in designing an apple handling or packing systems?).

The question will comprise 16% of the assessment for this subject. Marks will be allocated according to the following three criteria:

• General presentation and layout, grammar, spelling, logic of the presentation (20 marks)
• Accuracy and appropriateness of factual material (100 marks)
• Discussion and interpretation of the material (40 marks).

QUESTION 2: Design and write twenty multiple-choice questions related to any topics from any of the modules covered in this course. Each question should provide (only) one correct or best answer for four answers. The correct or best answer should be bolded. These questions should also not repeat the questions in the studybook or the examples below:

1. Grading operations of products may be defined as:

• The removal of contaminants
• Separation based on product size and weight
• Separation based on differing quality characteristics
• Cutting a flat edge on the product for display

2. Choice of material for food packaging containers is based on:

• Strength
• Ability to withstand the environment
• Barrier properties
• All of the above

3. The most common used grain storage facility in Australia is:

• Sheds
• Pads
• Steel silos
• Harvest bags.
