Please check it and give me right answer.

2 and 4 are wrong.

1. In order to meet their goals, Olympic hopefuls require persistence as they train and **perseverance** in the face of obstacles.

To find the correct answer, we need to understand the meaning of the word perseverance, which is the correct word in this context. Perseverance means the continued effort to achieve something despite difficulties or obstacles. In the given sentence, the word "perseverance" fits perfectly because Olympic hopefuls need to continue their training and remain committed even when faced with challenges.

2. Readers must leave the library **premises** by the stated closing time unless permissions for after-hour access has been granted.
To find the correct answer, we need to understand the meaning of the word premises, which is the correct word in this context. Premises refer to the building and land surrounding an institution or business. In the given sentence, the word "premises" fits perfectly because readers must leave the library building and its surrounding area by the stated closing time.

3. Beneath his withdrawn and **stifle** exterior, Collin was compassionate and affectionate.
To find the correct answer, we need to understand the meaning of the word weary, which is the correct word in this context. Weary means physically or mentally exhausted or fatigued. In the given sentence, the word "weary" fits perfectly because it describes Collin's exterior as exhausted or fatigued. The word "stifle" does not fit the context.

4. Nothing stirred over the vast **expanse** of grassland, except a pair of lionesses, which roared loudly from a rock behind us.
To find the correct answer, we need to understand the meaning of the word expanse, which is the correct word in this context. Expanse means a wide and open area or stretch of land. In the given sentence, the word "expanse" fits perfectly because it emphasizes the vastness and openness of the grassland. The other words mentioned (premises, stifle, weary, writhe) do not fit the context.
