Passage Reference: m. But by 1973. bad weather plus a realization of the limitations of this increase in yield caused a return to pessimism.

Common Mistake: Students often write early 1960s because the passage mentions that period. That is a Context shift trap because the text says per capita production was already inadequate then, not at its highest.

Paraphrasing: Passage: 'by 1973 ... return to pessimism' = Question: 'When was the per capita food production the highest?'

Tips: For date questions, look for before/after clues like 'by' or 'since' to infer the correct year.

Key Vocabulary:

• pessimism = loss of hope
• optimism = feeling hopeful

Question Focus: Listing food problems - first problem mentioned

Correct Answer: quantity

Passage Reference: . There appear to be five food problems. First, there is the problem of quantity - of every human being getting enough calories to provide him with the energy to work and progress.

Why this is correct: The passage clearly says, 'First, there is the problem of quantity', which matches the first food problem.

Common Mistake: Writing quality here is a Wrong order trap because quality is mentioned second, not first.

Paraphrasing: Passage: 'problem of quantity' = Question: 'Name food problems'

Tips: When a question asks for a list, follow the exact order in the passage.

Key Vocabulary:

• quantity = amount
• calories = energy from food

Question Focus: Second food problem

Correct Answer: quality

Passage Reference: . Second, there is that of quality - of everyone getting enough protein, vitamins, and necessary minerals.

Why this is correct: The passage says, 'Second, there is that of quality', so quality is the correct answer.

Common Mistake: Some students write nutrition, but that word is not used in the passage. This is a Synonym trap.

Paraphrasing: Passage: 'problem of quality' = Question: 'Name food problems'

Tips: Always copy the exact word from the passage, not a synonym.

Key Vocabulary:

• quality = how good something is
• minerals = essential nutrients

Question Focus: Identifying another listed food problem

Correct Answer: poverty

Passage Reference: . Then there is the problem of poverty: many people in developing countries do not have money to buy food in sufficient quantity and of sufficient quality.

Why this is correct: The passage states, 'Then there is the problem of poverty', so the correct answer is poverty.

Common Mistake: Students sometimes write money, but the passage talks about poverty as the problem. This is a Partial truth trap.

Paraphrasing: Passage: 'problem of poverty' = Question: 'Name food problems'

Tips: Look for phrases like 'there is the problem of...' to spot answers quickly.

Key Vocabulary:

• poverty = being very poor
• sufficient = enough

Question Focus: Food problem related to transport and storage

Correct Answer: distribution

Passage Reference: . Next, there is the matter of distribution: we have to find satisfactory ways of transporting, storing and issuing food.

Why this is correct: The passage mentions 'the matter of distribution', which matches this gap.

Common Mistake: Writing transport is tempting, but transport is only part of distribution. This is a Partial truth trap.

Paraphrasing: Passage: 'matter of distribution' = Question: 'Name food problems'

Tips: If several examples are given, the answer is usually the category word, not one example.

Key Vocabulary:

• distribution = sharing and delivering
• issuing = giving out

Question Focus: Environmental food problem

Correct Answer: ecological side-effects

Passage Reference: . And last, we must find ways of avoiding ecological side-effects. In other words, we must be able to grow enough food without further degrading our land, water and air.

Why this is correct: The final food problem is clearly named as 'ecological side-effects' in the passage.

Common Mistake: Students may write pollution, but that word is not used. This is a Synonym trap.

Paraphrasing: Passage: 'ecological side-effects' = Question: 'Name food problems'

Tips: Hyphenated words count as one word in IELTS.

Key Vocabulary:

• ecological = related to the environment
• side-effects = unintended results

Question Focus: Method to increase yield per hectare

Correct Answer: developing new hybrids

Passage Reference: re by developing or selecting new genetic hybrids of plants (the 'Green Revolution'), by increasing the use of fertilizers, water, pesticides and herbicides, and by using modem agricultural and manage

Why this is correct: The passage explains yield increases come from developing or selecting new genetic hybrids, shortened here to developing new hybrids.

Common Mistake: Writing Green Revolution is a Context shift trap because it names the movement, not the method.

Paraphrasing: Passage: 'developing or selecting new genetic hybrids' = Question: 'attempts made to increase the yield per hectare'

Tips: You can shorten phrases, but only using words that appear in the passage.

Key Vocabulary:

• hybrids = mixed plant types
• yield = amount produced

Question Focus: Agricultural input to raise yield

Correct Answer: increasing the use of fertilizers

Passage Reference: ), by increasing the use of fertilizers, water, pesticides and herbicid

Why this is correct: The passage lists 'increasing the use of fertilizers' as one method to raise yield per hectare.

Common Mistake: Writing only fertilizers misses the action. This is a Grammar fit trap.

Paraphrasing: Passage: 'increasing the use of fertilizers' = Question: 'attempts made to increase the yield per hectare'

Tips: Check the grammar pattern of the list and match it.

Key Vocabulary:

• fertilizers = plant nutrients
• increase = make more

Question Focus: Another yield-increasing input

Correct Answer: water

Passage Reference: ), by increasing the use of fertilizers, water, pesticides and herbicid

Why this is correct: The passage includes water as part of the inputs used to increase yield.

Common Mistake: Students sometimes skip this because it seems too simple. That is an Overthinking trap.

Paraphrasing: Passage: 'fertilizers, water, pesticides' = Question: 'attempts made to increase the yield per hectare'

Tips: Do not ignore single common words if they are clearly listed.

Key Vocabulary:

• irrigation = supplying water
• input = something added

Question Focus: Chemical methods to improve yield

Correct Answer: pesticides and herbicides

Passage Reference: ), by increasing the use of fertilizers, water, pesticides and herbicid

Why this is correct: The passage explicitly lists pesticides and herbicides as methods to raise yield.

Common Mistake: Writing only pesticides is incomplete. This is a Partial truth trap.

Paraphrasing: Passage: 'pesticides and herbicides' = Question: 'attempts made to increase the yield per hectare'

Tips: If two items are joined by and in the passage, include both.

Key Vocabulary:

• pesticides = chemicals against pests
• herbicides = chemicals against weeds

Question Focus: Management methods to increase yield

Correct Answer: using modem techniques

Passage Reference: s, and by using modem agricultural and management techniques in poorer countries.

Why this is correct: The passage ends the list with 'using modem agricultural and management techniques', shortened here to using modem techniques.

Common Mistake: Students may write technology, which is not the exact wording. This is a Synonym trap.

Paraphrasing: Passage: 'using modem agricultural and management techniques' = Question: 'attempts made to increase the yield per hectare'

Tips: You can omit extra adjectives if the core words stay the same as the passage.

Key Vocabulary:

• modem = modern
• techniques = methods

General Tips:

• Summary and note completion questions follow passage order. Use the previous answer to find the next.
• Always copy words from the passage. Do not invent synonyms.
• Check the word limit carefully. Extra words make the answer wrong.
• Look at grammar clues like lists, -ing forms, or plural nouns.
