1 Kings 10: 1-13
When the queen of Sheba heard of the fame of Solomon, (fame due to the name of the Lord), she came to test him with hard questions. She came to Jerusalem with a very great retinue, with camels bearing spices, and very much gold, and precious stones; and when she came to Solomon, she told him all that was on her mind.
What was on her mind? What did she want to know? What was hard about the questions?
Did she want to test Solomon (i.e. did she know the answers to her questions) or did she want answers that no-one else had been able to give?
Solomon answered all her questions; there was nothing hidden from the king that he could not explain to her. When the queen of Sheba had observed all the wisdom of Solomon, the house that he had built, the food of his table, the seating of his officials, and the attendance of his servants, their clothing, his valets, and his burnt-offerings that he offered at the house of the Lord, there was no more spirit in her.
that sounds more as if she was testing Solomon - whereas, with the questions, it sounded more as if she was looking for answers
So she said to the king, ‘The report was true that I heard in my own land of your accomplishments and of your wisdom, but I did not believe the reports until I came and my own eyes had seen it. Not even half had been told me; your wisdom and prosperity far surpass the report that I had heard. Happy are your wives! Happy are these your servants, who continually attend you and hear your wisdom! Blessed be the Lord your God, who has delighted in you and set you on the throne of Israel! Because the Lord loved Israel for ever, he has made you king to execute justice and righteousness.’ Then she gave the king one hundred and twenty talents of gold, a great quantity of spices, and precious stones; never again did spices come in such quantity as that which the queen of Sheba gave to King Solomon.
Moreover, the fleet of Hiram, which carried gold from Ophir, brought from Ophir a great quantity of almug wood and precious stones. From the almug wood the king made supports for the house of the Lord, and for the king’s house, lyres also and harps for the singers; no such almug wood has come or been seen to this day.
Meanwhile, King Solomon gave to the queen of Sheba every desire that she expressed, as well as what he gave her out of Solomon’s royal bounty. Then she returned to her own land, with her servants.

Acts 13: 1-13
Now in the church at Antioch there were prophets and teachers: Barnabas, Simeon who was called Niger, Lucius of Cyrene, Manaen a member of the court of Herod the ruler, and Saul. While they were worshipping the Lord and fasting, the Holy Spirit said, ‘Set apart for me Barnabas and Saul for the work to which I have called them.’ Then after fasting and praying they laid their hands on them and sent them off.

So, being sent out by the Holy Spirit, they went down to Seleucia; and from there they sailed to Cyprus. When they arrived at Salamis, they proclaimed the word of God in the synagogues of the Jews. And they had John also to assist them. When they had gone through the whole island as far as Paphos, they met a certain magician, a Jewish false prophet, named Bar-Jesus. He was with the proconsul, Sergius Paulus, an intelligent man, who summoned Barnabas and Saul and wanted to hear the word of God.
another one who wants answers
But the magician Elymas (for that is the translation of his name) opposed them and tried to turn the proconsul away from the faith. But Saul, also known as Paul, filled with the Holy Spirit, looked intently at him and said, ‘You son of the devil, you enemy of all righteousness, full of all deceit and villainy, will you not stop making crooked the straight paths of the Lord? And now listen—the hand of the Lord is against you, and you will be blind for a while, unable to see the sun.’ Immediately mist and darkness came over him, and he went about groping for someone to lead him by the hand. When the proconsul saw what had happened, he believed, for he was astonished at the teaching about the Lord.

Then Paul and his companions set sail from Paphos and came to Perga in Pamphylia. John, however, left them and returned to Jerusalem.
