How to Answer Fill in the Blanks (Drag-and-Drop) – Step by Step
1
Read the Passage Completely First:
Always read the entire passage from start to finish before looking at the blanks or word options. This allows you to understand the general theme, which, for this task, is “renewable energy solutions.” Skimming quickly helps you see how the ideas connect. If you read only around the blanks, you might miss the main point—such as whether the passage is comparing energy sources, explaining a problem, or describing a solution. In PTE Academic, the passages are short (about 120 words) but packed with academic vocabulary. Reading fully gives you a big-picture view, so you’re ready to predict missing words with more confidence.

2
Spot the Grammar of Each Blank:
Look closely at the words before and after each blank. Decide if you need a noun, verb, adjective, adverb, connector, or preposition. For example, in “Renewable energy is a ___ solution,” only an adjective fits the blank. Being able to label the grammar narrows down your choices and stops you from using words that “sound right” but don’t fit the sentence structure. PTE Academic often puts similar words as distractors, so pay attention!

PTE Academic often puts similar words as distractors, so pay attention!

Predict the Missing Word Before Looking at Choices:
Before you even look at the word bank, try to imagine what kind of word makes sense. Is it a type of energy? A result? A process? For example, “Wind and solar are ___ sources of power” clearly needs a positive or descriptive adjective. If you predict first, you won’t be distracted by wrong options.

4
Examine All Word Choices Thoroughly:
Look at each word in the list. Think about its meaning and grammar. Is it a verb when you need a noun? Does it match the topic? Some options are designed to trick you—for example, “efficiency” vs. “effective.” Eliminate those that definitely cannot fit.

5
Use Context Clues in the Sentences:
Academic texts, like those in the PTE, are full of context clues: words that signal cause/effect, comparison, or contrast (e.g., “however,” “for instance,” “due to”). Before filling the blank, check what the sentence before and after is saying. If the blank connects two ideas, maybe you need a linking word, not just a noun.

Before filling the blank, check what the sentence before and after is saying. If the blank connects two ideas, maybe you need a linking word, not just a noun.
6
Look for Collocations and Fixed Expressions:
English has many set phrases, especially in academic writing about energy, like “renewable resource,” “reduce emissions,” “energy efficiency,” or “global challenge.” If you spot part of a familiar phrase before or after a blank, that’s a clue. Collocations are a frequent test point in PTE Academic.

7
Test Each Option in the Blank:
Drag and drop one option at a time into the blank. Read the sentence aloud in your head. Does it sound natural? Is the grammar correct? If it doesn’t work, try another word. Never “force” a word just because you want to use it up. There’s only one correct answer for each blank in real PTE Academic.

Check the Logical Flow of the Whole Passage:
After you fill all the blanks, reread the passage from start to end. Does it make sense as a whole? Is the argument or explanation logical? If a sentence is awkward, try changing your choice for that blank.

Look for Distractors and Close Meanings:
PTE Academic always includes tricky words that almost fit. Watch out for words with similar meanings but different usage, like “efficient” vs. “effective,” “reduce” vs. “limit.” If you’re stuck, eliminate words that are clearly wrong, then focus on what’s left.

Answer Key & Step-by-Step Explanation
See exactly how to solve this PTE Academic Fill in the Blanks (Drag-and-Drop) question.
Read the detailed academic logic, vocabulary, and grammar for each blank. Deep explanations help you master word patterns, collocations, and PTE Academic strategies.
1st Blank:
change ("combating climate change")
“Climate change” is a set academic phrase. It means long-term shifts in global temperatures and weather patterns, mostly due to human activity.
The word “change” is a noun here, following “climate.” Other options like “demand” or “carbon” would be ungrammatical and nonsensical.
Academic reading always tests if you can identify common environmental science collocations. This one appears in almost every PTE Academic energy or environment passage.
The context signals that renewable energy is a response to a global challenge; “change” matches both the scientific and practical sense.
Tip: When you see “climate ___”, “change” is almost always correct in environmental English.
2nd Blank:
renewable ("examples of renewable sources")
“Renewable sources” means energy sources that replenish naturally and are not depleted by use, such as wind, solar, and hydropower.
The grammar pattern is “adjective + sources.” “Renewable” is the only option that logically and grammatically fits here.
Distractors like “carbon,” “demand,” or “reliable” do not describe “sources” in energy science.
In PTE Academic, recognizing set academic collocations such as “renewable sources” is a sign of higher-level reading skill.
Tip: Learn the most common adjective-noun pairs in energy/environment topics—these come up in every real exam.
3rd Blank:
grids ("existing grids")
“Grids” here means the interconnected system that delivers electricity from producers to consumers.
The full collocation is “energy grids” or “power grids,” often used in discussions of modernizing infrastructure for renewables.
“Integrating solutions into existing grids” is a challenge because older grids were designed for fossil fuel sources, not variable renewables.
Grammar: “Grids” is a plural noun, matching “existing” (adjective) and the sentence structure.
Tip: In energy passages, look for context clues about infrastructure and distribution; “grids” is a technical word with a specific meaning.
4th Blank:
advancements ("technological advancements")
“Technological advancements” means new inventions, progress, or breakthroughs in technology.
This collocation is extremely frequent in academic and scientific writing. “Advancements” is a plural noun; “technological” is the adjective.
The sentence discusses how better technology helps energy storage—matching perfectly with “advancements.”
Tip: “Technological advancements” is often tested as a phrase in high-level English reading for both vocabulary and collocation knowledge.
5th Blank:
reliable ("increasingly reliable")
“Reliable” is an adjective meaning able to be depended on to work well or to give the correct result.
The phrase “increasingly reliable” describes how improvements have made renewable energy storage more dependable over time.
Grammar: The adverb “increasingly” is almost always followed by an adjective (“reliable”).
In the energy context, “reliable” means the supply can be counted on, even with variable production (e.g., when there’s no sun or wind).
Tip: Look for pairs like “increasingly + adjective” as a common academic grammar pattern.
Key Strategies for Fill in the Blanks (Drag-and-Drop):
Step 1: Always predict the grammar and meaning before looking at the options.
Step 2: Notice set phrases and collocations—these are almost always the answer in real PTE Academic.
Step 3: Eliminate distractors by testing the sentence for meaning and grammatical fit.
Step 4: Review the answer key and explanations for every mistake—this is how top scorers improve fastest!
