Type 3 Conditional (Fill In)

Explanation
This question is about a hypothetical situation in the past. The correct answer uses the past perfect tense "had been" to indicate that the food was bad at a certain point in the past. The second part of the answer uses the conditional form "would not have eaten" and its contraction "wouldn't have eaten" to show that if the food had been bad, the speaker and others would not have consumed it.

Explanation
The correct answer is "had been; would have seen." This is because the sentence is in the third conditional form, which is used to talk about hypothetical situations in the past. "Had been" is the past perfect form of the verb "to be" and is used to show that the action of going to London happened before the action of seeing Big Ben. "Would have seen" is the conditional form of the verb "to see" and is used to show the hypothetical outcome of seeing Big Ben if they had gone to London.

Explanation
The correct answer is "had not broken down; would not have missed" and "hadn't broken down; wouldn't have missed". This is because the sentence is in the third conditional form, which is used to talk about hypothetical situations in the past. In this case, the car breaking down is the hypothetical situation. The use of "had not broken down" and "hadn't broken down" indicates that the car did break down in the past, and the use of "would not have missed" and "wouldn't have missed" indicates the result of the hypothetical situation, which is not missing the plane.

Explanation
The correct answer is "had showed; would not have crossed, had showed; wouldn't have crossed." This is because the sentence is in the past perfect tense, indicating an action that occurred before another action in the past. "Had showed" is the past perfect tense of "show," indicating that showing the visa happened before the action of crossing the border. "Would not have crossed" and "wouldn't have crossed" are both in the conditional perfect tense, indicating that the crossing of the border would not have happened if the visa had not been shown.

Explanation
The correct answer is "would have stayed; had rained". This is because the sentence is in the past conditional tense, indicating a hypothetical situation in the past. "Would have stayed" is the correct form of the verb "stay" in the past conditional, and "had rained" is the correct form of the verb "rain" in the past perfect tense.

Explanation
The correct answer is "had not been; would have built" and "hadn't been; would have built". These are the correct forms of the past perfect tense and the conditional perfect tense. The first part of the sentence suggests that the weather was very cold in the past, and the second part implies that if the weather had not been so cold, they would have been able to build the bridge.

Explanation
The correct answer is "had seen; would have stopped." This is because the sentence is in the past unreal conditional form. It suggests that if the driver had seen the red traffic light (which he didn't), he would have stopped (but he didn't). The use of "had seen" in the past perfect tense indicates that the action of seeing the red light occurred before the action of not stopping. "Would have stopped" in the conditional perfect tense shows the hypothetical outcome that would have taken place if the driver had seen the light.

Explanation
This sentence is a conditional statement in the past unreal condition. The use of "would have told" suggests that the speaker did not actually tell her because she did not ask politely. The phrase "had asked" is used to indicate the past unreal condition, meaning that she did not ask politely in the past.

Explanation
This sentence is a conditional statement in the past unreal condition. It suggests that Jill would have been very excited if Jack had rung her up. The phrase "would have been" is used to express the hypothetical result in the past, and "had rung" is the past perfect tense used to indicate the action that should have happened before the hypothetical result.

Explanation
The correct answer is "had not left; would not have run away, hadn't left; wouldn't have run away." This answer follows the correct structure for the third conditional sentence. The first part of the sentence uses "had not left" or "hadn't left" to indicate that Ben did not leave the gate open. The second part of the sentence uses "would not have run away" or "wouldn't have run away" to show the hypothetical result of the gate not being left open.
