All questions

Question 1

Choose the word that shows earlier time:   we eat lunch, we wash hands.

  1. After
  2. Because
  3. Or
  4. Before (correct answer)
Explanation: This question tests using coordinating and subordinating conjunctions (CCSS.L.3.1.h). The conjunction 'before' is a subordinating conjunction that shows time sequence with one action happening earlier. Coordinating conjunctions (and but or so) join equal ideas like adding two items or showing simple contrast. Subordinating conjunctions (because when if before after while although) connect unequal ideas showing relationships like cause-effect time sequences or conditions. In this sentence we have two ideas: we eat lunch and we wash hands. The relationship between them is time sequence - washing hands happens earlier than eating lunch. We need a conjunction that shows this temporal order. Choice D is correct because 'before' properly shows that hand-washing occurs prior to eating lunch. This makes the sentence logical and clear: the hygiene step comes first, then the meal. Choice A is incorrect because it shows the opposite time sequence. Using 'after' would mean we wash hands following lunch, which reverses the proper hygiene order. Students confuse these when they don't carefully think about which action comes first in time. To help students: First identify the relationship between the two ideas (Are we adding? Contrasting? Showing cause? Showing time?). Then choose the conjunction that matches: Addition→and. Contrast→but. Choice→or. Cause/reason→because or so. Time→when before after. Condition→if. Teach time sequence words: before = first action mentioned happens earlier, after = first action mentioned happens later. Practice: We brush teeth   we go to bed (before - brushing happens first). Watch for: confusing before/after / not thinking about logical time order.

Question 2

Which word shows earlier time? "  we eat lunch, we wash our hands."

  1. After
  2. Because
  3. Before (correct answer)
  4. Or
Explanation: Washing hands happens first, so "Before we eat lunch, we wash our hands" shows the earlier time. Choice C is correct. "After" would make washing happen later, "Because" gives a reason (not time), and "Or" shows a choice, so none shows earlier time.

Question 3

Complete to show contrast: Jamal wanted to play,   it started raining.

  1. and
  2. because
  3. but (correct answer)
  4. when
Explanation: This question tests using coordinating and subordinating conjunctions (CCSS.L.3.1.h). The conjunction 'but' is a coordinating conjunction that shows contrast. Coordinating conjunctions (and but or so) join equal ideas like adding two items or showing simple contrast. Subordinating conjunctions (because when if before after while although) connect unequal ideas showing relationships like cause-effect time sequences or conditions. In this sentence we have two ideas: Jamal wanted to play and it started raining. The relationship between them is contrast. We need a conjunction that shows this relationship specifically. Choice C is correct because 'but' properly shows the contrast. But shows contrast between two different ideas. This makes the sentence logical and clear. Choice A is incorrect because it shows addition. Using 'and' would mean adding ideas without contrast, like both happening together positively. Students confuse these when they don't identify the relationship between ideas. To help students: First identify the relationship between the two ideas (Are we adding? Contrasting? Showing cause? Showing time?). Then choose the conjunction that matches: Addition→and. Contrast→but. Choice→or. Cause/reason→because or so. Time→when before after. Condition→if. Teach FANBOYS for coordinating (For And Nor But Or Yet So) and common subordinating (because when if before after). Practice: I like X   Y (and). I wanted X   Y happened (but). I did X   Y was true (because). Watch for: using and for everything / not recognizing cause-effect needs because or so / confusing time words (before/after/when).

Question 4

Choose the conjunction that adds ideas: Carlos likes science,   he likes art.

  1. but
  2. because
  3. and (correct answer)
  4. if
Explanation: This question tests using coordinating and subordinating conjunctions (CCSS.L.3.1.h). The conjunction 'and' is a coordinating conjunction that shows addition. Coordinating conjunctions (and but or so) join equal ideas like adding two items or showing simple contrast. Subordinating conjunctions (because when if before after while although) connect unequal ideas showing relationships like cause-effect time sequences or conditions. In this sentence we have two ideas: Carlos likes science and he likes art. The relationship between them is addition - we're adding two things Carlos likes. We need a conjunction that shows this additive relationship. Choice C is correct because 'and' properly shows that Carlos likes both subjects, adding them together. This makes the sentence logical and clear: 'Carlos likes science, and he likes art.' Choice A is incorrect because it shows contrast. Using 'but' would suggest liking science opposes or conflicts with liking art, which doesn't make sense when someone enjoys both. Students confuse these when they think any two different things need 'but'. To help students: First identify the relationship between the two ideas (Are we adding? Contrasting? Showing cause? Showing time?). Then choose the conjunction that matches: Addition→and. Contrast→but. Choice→or. Cause/reason→because or so. Time→when before after. Condition→if. Use 'and' to list or add similar things, 'but' only for opposing ideas. Practice: I like X   Y (and for adding). I like X   not Y (but for contrast). Watch for: overusing 'but' / not recognizing when we're simply adding items to a list.

Question 5

Choose the conjunction that adds ideas: Chen likes art   he likes music.

  1. but
  2. and (correct answer)
  3. because
  4. if
Explanation: This question tests using coordinating and subordinating conjunctions (CCSS.L.3.1.h). The conjunction 'and' is a coordinating conjunction that shows addition. Coordinating conjunctions (and but or so) join equal ideas like adding two items or showing simple contrast. Subordinating conjunctions (because when if before after while although) connect unequal ideas showing relationships like cause-effect time sequences or conditions. In this sentence we have two ideas: Chen likes art and he likes music. The relationship between them is addition - we're adding two things Chen enjoys. We need a conjunction that shows this additive relationship. Choice B is correct because 'and' properly shows that Chen likes both art and music, adding these interests together. This makes the sentence logical and clear: Chen has multiple interests that we're listing. Choice A is incorrect because it shows contrast. Using 'but' would suggest that liking art and liking music are somehow opposing or contradictory, which doesn't make logical sense. Students confuse these when they think any two different things need 'but' rather than recognizing that 'and' adds compatible ideas. To help students: First identify the relationship between the two ideas (Are we adding? Contrasting? Showing cause? Showing time?). Then choose the conjunction that matches: Addition→and. Contrast→but. Choice→or. Cause/reason→because or so. Time→when before after. Condition→if. Teach that 'and' adds similar or compatible ideas, while 'but' shows opposition. Practice: I like pizza   I like pasta (and - both are liked). Watch for: overusing 'but' / not recognizing when ideas complement rather than contrast.

Question 6

Complete to show a reason: We stayed inside   it was raining.

  1. because (correct answer)
  2. or
  3. but
  4. and
Explanation: This question tests using coordinating and subordinating conjunctions (CCSS.L.3.1.h). The conjunction 'because' is a subordinating conjunction that shows cause/reason. Coordinating conjunctions (and but or so) join equal ideas like adding two items or showing simple contrast. Subordinating conjunctions (because when if before after while although) connect unequal ideas showing relationships like cause-effect time sequences or conditions. In this sentence we have two ideas: We stayed inside and it was raining. The relationship between them is cause-effect - the rain is the reason for staying inside. We need a conjunction that shows this causal relationship. Choice A is correct because 'because' properly shows that the rain caused us to stay inside. This makes the sentence logical and clear: 'We stayed inside because it was raining.' Choice C is incorrect because it shows contrast. Using 'but' would mean staying inside opposes or contrasts with raining, which doesn't make logical sense. Students confuse these when they don't identify that one event causes the other. To help students: First identify the relationship between the two ideas (Are we adding? Contrasting? Showing cause? Showing time?). Then choose the conjunction that matches: Addition→and. Contrast→but. Choice→or. Cause/reason→because or so. Time→when before after. Condition→if. Ask 'Why did this happen?' If the second part answers why, use 'because'. Practice: We did X   Y happened (because). Watch for: using 'but' instead of 'because' / not recognizing cause-effect relationships.

Question 7

Complete to show time:   the bell rings, we line up quietly.

  1. Because
  2. When (correct answer)
  3. Or
  4. So
Explanation: This question tests using coordinating and subordinating conjunctions (CCSS.L.3.1.h). The conjunction 'when' is a subordinating conjunction that shows time relationship. Coordinating conjunctions (and but or so) join equal ideas like adding two items or showing simple contrast. Subordinating conjunctions (because when if before after while although) connect unequal ideas showing relationships like cause-effect time sequences or conditions. In this sentence we have two ideas: the bell rings and we line up quietly. The relationship between them is time - lining up happens at the time the bell rings. We need a conjunction that shows this timing relationship. Choice B is correct because 'when' properly shows that lining up occurs at the time of the bell ringing. This makes the sentence logical and clear: 'When the bell rings, we line up quietly.' Choice A is incorrect because it shows cause/reason. Using 'because' would mean we line up due to the bell ringing as a reason, not timing. Students confuse these when they mix up time relationships with cause-effect. To help students: First identify the relationship between the two ideas (Are we adding? Contrasting? Showing cause? Showing time?). Then choose the conjunction that matches: Addition→and. Contrast→but. Choice→or. Cause/reason→because or so. Time→when before after. Condition→if. Ask 'Is this about timing or reason?' Time words answer 'when' something happens. Practice:   X happens, Y occurs (when). Watch for: using 'because' for time relationships / not recognizing simultaneous or sequential timing.

Question 8

Which word correctly completes this sentence?   it snows, school may close.

  1. When
  2. Unless
  3. If (correct answer)
  4. Since
Explanation: If is correct because it shows that school closing depends on whether it snows. When suggests the snow is a certain future event rather than a possibility, which does not match the word may in the sentence. Unless reverses the meaning, suggesting school closes only when it does not snow. Since introduces a reason or a starting point in time, not a possibility that may or may not happen.

Question 9

Which word correctly completes this sentence to show that two things happen at the same time?   Yuki reads, Marcus draws.

  1. While (correct answer)
  2. Because
  3. Or
  4. So
Explanation: While is correct because it shows that Yuki's reading and Marcus's drawing are happening at the same time. Because introduces a reason, but nothing in the sentence explains why either action is happening. Or presents a choice between the two actions rather than showing they occur together. So shows a result, which does not match two things happening at the same time.

Question 10

Which word correctly completes the sentence to show a result? Chen finished his work,   he went to recess.

  1. so (correct answer)
  2. but
  3. when
  4. or
Explanation: So is correct because it shows that going to recess was the result of finishing his work. But shows contrast, not a result. When shows a time relationship, not a result. Or shows a choice between two options, not a result.

Question 11

Which word correctly completes the sentence to show a choice? Do you want an apple   a banana?

  1. and
  2. because
  3. or (correct answer)
  4. so
Explanation: Or is correct because it shows a choice between an apple and a banana. And would show that both items are wanted together, not a choice. Because shows a reason, not a choice. So shows a result, not a choice.

Question 12

Which word correctly completes this sentence and shows the reason Maya wore boots? Maya wore boots   the ground was wet.

  1. because (correct answer)
  2. or
  3. before
  4. but
Explanation: Because is correct because it introduces the reason Maya wore boots, which was the wet ground. Or presents a choice between two options and does not give a reason. Before shows a time order between two events, not a cause. But shows contrast between two ideas, which does not explain why Maya wore boots.

Question 13

Which word correctly completes the sentence to show a choice? You can read quietly   draw a picture.

  1. and
  2. because
  3. or (correct answer)
  4. so
Explanation: Or is correct because it shows a choice between reading quietly and drawing a picture. And would show that both actions happen together, not a choice. Because shows a reason, not a choice. So shows a result, not a choice.

Question 14

Which word correctly completes this sentence to show a result? Keisha finished early,   she helped a friend.

  1. because
  2. so (correct answer)
  3. but
  4. or
Explanation: So is correct because it is a coordinating conjunction used to show a result of something that happened first. Because shows a reason and would reverse the logic of the sentence, since finishing early is the cause, not the result. But shows contrast, which does not match the sentence. Or presents a choice between two options, which does not fit here.

Question 15

Choose the word that shows two actions at once:   Yuki read, Amir drew.

  1. While (correct answer)
  2. Because
  3. Or
  4. So
Explanation: This question tests using coordinating and subordinating conjunctions (CCSS.L.3.1.h). The conjunction 'while' is a subordinating conjunction that shows time. Coordinating conjunctions (and but or so) join equal ideas like adding two items or showing simple contrast. Subordinating conjunctions (because when if before after while although) connect unequal ideas showing relationships like cause-effect time sequences or conditions. In this sentence we have two ideas: Yuki read and Amir drew. The relationship between them is time. We need a conjunction that shows this relationship specifically. Choice A is correct because 'while' properly shows the two actions at once. While shows two actions at once. This makes the sentence logical and clear. Choice B is incorrect because it shows cause. Using 'because' would mean one action caused the other, not simultaneous. Students confuse these when they don't identify the relationship between ideas. To help students: First identify the relationship between the two ideas (Are we adding? Contrasting? Showing cause? Showing time?). Then choose the conjunction that matches: Addition→and. Contrast→but. Choice→or. Cause/reason→because or so. Time→when before after. Condition→if. Teach FANBOYS for coordinating (For And Nor But Or Yet So) and common subordinating (because when if before after). Practice: I like X   Y (and). I wanted X   Y happened (but). I did X   Y was true (because). Watch for: using and for everything / not recognizing cause-effect needs because or so / confusing time words (before/after/when).

Question 16

Complete to show earlier time:   we eat lunch, we wash our hands.

  1. After
  2. Before (correct answer)
  3. Because
  4. Or
Explanation: This question tests using coordinating and subordinating conjunctions (CCSS.L.3.1.h). The conjunction 'before' is a subordinating conjunction that shows time. Coordinating conjunctions (and but or so) join equal ideas like adding two items or showing simple contrast. Subordinating conjunctions (because when if before after while although) connect unequal ideas showing relationships like cause-effect time sequences or conditions. In this sentence we have two ideas: we eat lunch and we wash our hands. The relationship between them is time. We need a conjunction that shows this relationship specifically. Choice B is correct because 'before' properly shows the earlier time. Before/After: sequence (before we eat / after school). This makes the sentence logical and clear. Choice A is incorrect because it shows later time. Using 'after' would mean washing hands after eating, reversing the sequence. Students confuse these when they don't identify the relationship between ideas. To help students: First identify the relationship between the two ideas (Are we adding? Contrasting? Showing cause? Showing time?). Then choose the conjunction that matches: Addition→and. Contrast→but. Choice→or. Cause/reason→because or so. Time→when before after. Condition→if. Teach FANBOYS for coordinating (For And Nor But Or Yet So) and common subordinating (because when if before after). Practice: I like X   Y (and). I wanted X   Y happened (but). I did X   Y was true (because). Watch for: using and for everything / not recognizing cause-effect needs because or so / confusing time words (before/after/when).

Question 17

Complete to show why: Keisha wore boots   it was raining outside.

  1. because (correct answer)
  2. or
  3. but
  4. and
Explanation: This question tests using coordinating and subordinating conjunctions (CCSS.L.3.1.h). The conjunction 'because' is a subordinating conjunction that shows cause/reason. Coordinating conjunctions (and but or so) join equal ideas like adding two items or showing simple contrast. Subordinating conjunctions (because when if before after while although) connect unequal ideas showing relationships like cause-effect time sequences or conditions. In this sentence we have two ideas: Keisha wore boots and it was raining outside. The relationship between them is cause-effect - the rain is the reason why Keisha wore boots. We need a conjunction that shows this causal relationship. Choice A is correct because 'because' properly shows that the rain caused Keisha to wear boots. This makes the sentence logical and clear: the rain is the reason for wearing boots. Choice C is incorrect because it shows contrast. Using 'but' would mean wearing boots opposes or contrasts with the rain, which doesn't make logical sense. Students confuse these when they don't recognize that one action (wearing boots) is a response to a condition (rain). To help students: First identify the relationship between the two ideas (Are we adding? Contrasting? Showing cause? Showing time?). Then choose the conjunction that matches: Addition→and. Contrast→but. Choice→or. Cause/reason→because or so. Time→when before after. Condition→if. Teach FANBOYS for coordinating (For And Nor But Or Yet So) and common subordinating (because when if before after). Practice: I did X   Y was happening (because shows the reason). Watch for: using 'but' when showing cause / not recognizing that rain causes the boot-wearing decision.

Question 18

Choose the conjunction that shows a result: Sofia studied hard,   she got an A.

  1. because
  2. so (correct answer)
  3. when
  4. or
Explanation: This question tests using coordinating and subordinating conjunctions (CCSS.L.3.1.h). The conjunction 'so' is a coordinating conjunction that shows result or consequence. Coordinating conjunctions (and but or so) join equal ideas like adding two items or showing simple contrast. Subordinating conjunctions (because when if before after while although) connect unequal ideas showing relationships like cause-effect time sequences or conditions. In this sentence we have two ideas: Sofia studied hard and she got an A. The relationship between them is cause-result - studying hard resulted in getting an A. We need a conjunction that shows this consequence relationship. Choice B is correct because 'so' properly shows that studying hard led to the result of getting an A. This makes the sentence logical and clear: 'Sofia studied hard, so she got an A.' Choice A is incorrect because it shows reason in the wrong direction. Using 'because' would mean Sofia studied hard because she got an A, reversing the cause and effect. Students confuse these when they mix up which event caused which. To help students: First identify the relationship between the two ideas (Are we adding? Contrasting? Showing cause? Showing time?). Then choose the conjunction that matches: Addition→and. Contrast→but. Choice→or. Cause/reason→because or so. Time→when before after. Condition→if. Remember: 'because' looks backward to the reason, 'so' looks forward to the result. Practice: X happened,   Y resulted (so). X happened   Y caused it (because). Watch for: confusing 'because' and 'so' / not identifying which is cause and which is effect.

Question 19

Choose the word that shows later time:   school ends, Maya goes home.

  1. After (correct answer)
  2. If
  3. But
  4. And
Explanation: This question tests using coordinating and subordinating conjunctions (CCSS.L.3.1.h). The conjunction 'after' is a subordinating conjunction that shows time sequence with one action happening later. Coordinating conjunctions (and but or so) join equal ideas like adding two items or showing simple contrast. Subordinating conjunctions (because when if before after while although) connect unequal ideas showing relationships like cause-effect time sequences or conditions. In this sentence we have two ideas: school ends and Maya goes home. The relationship between them is time sequence - going home happens following the end of school. We need a conjunction that shows this temporal order. Choice A is correct because 'after' properly shows that going home occurs following school ending. This makes the sentence logical and clear: first school ends, then Maya goes home. Choice B is incorrect because it shows condition rather than time sequence. Using 'if' would mean Maya only goes home sometimes when school ends (conditional), not regularly after school (temporal sequence). Students confuse these when they don't distinguish between regular time sequences and conditional situations. To help students: First identify the relationship between the two ideas (Are we adding? Contrasting? Showing cause? Showing time?). Then choose the conjunction that matches: Addition→and. Contrast→but. Choice→or. Cause/reason→because or so. Time→when before after. Condition→if. Teach that 'after' shows time order (this happens, then that), while 'if' shows possibility (maybe this will happen). Practice: We eat dinner   we finish homework (after - shows sequence). Watch for: using 'if' for regular sequences / not recognizing routine time patterns.

Question 20

Which conjunction shows a choice: Do you want an apple   a banana?

  1. and
  2. because
  3. or (correct answer)
  4. so
Explanation: This question tests using coordinating and subordinating conjunctions (CCSS.L.3.1.h). The conjunction 'or' is a coordinating conjunction that shows choice between options. Coordinating conjunctions (and but or so) join equal ideas like adding two items or showing simple contrast. Subordinating conjunctions (because when if before after while although) connect unequal ideas showing relationships like cause-effect time sequences or conditions. In this sentence we have two ideas: an apple and a banana. The relationship between them is choice - you can have one or the other. We need a conjunction that shows this alternative relationship. Choice C is correct because 'or' properly shows the choice between apple and banana. This makes the sentence logical and clear: 'Do you want an apple or a banana?' Choice A is incorrect because it shows addition. Using 'and' would mean you want both an apple and a banana together, not a choice between them. Students confuse these when they don't recognize that the question asks for selection between options. To help students: First identify the relationship between the two ideas (Are we adding? Contrasting? Showing cause? Showing time?). Then choose the conjunction that matches: Addition→and. Contrast→but. Choice→or. Cause/reason→because or so. Time→when before after. Condition→if. Look for clue words like 'Do you want' or 'Would you like' that signal a choice. Practice: Choose X   Y (or). I want X   Y together (and). Watch for: using 'and' when offering choices / not recognizing alternative options.
