In this task, you are given a multiple-choice question about healthcare. Answer the question based on your information and classify your answers into '1', '2', '3', and '4'.
One example: Question: A 13-year-old girl is operated on due to Hirschsprung illness at 3 months of age. Which of the following tumors is more likely to be present?
Options: <1> Abdominal neuroblastoma <2> Wilms tumor <3> Mesoblastic nephroma <4> Familial thyroid medullary carcinoma.
Solution is here: 2
Explanation: The answer to the given question should be a tumor, therefore Wilms tumor is the correct answer for the given question.

Now, solve this: Question: A particle charged in solution moves when it is placed in an electric field. The speed acquired by the solute under the influence of the applied voltage is the product of the apparent mobility of the solute and the applied field. With regard to this mobility, it can be stated that:
Options: <1> A neutral particle of small size will have a smaller mobility than a neutral one of large size. <2> A macromolecular polymer will have greater mobility than the corresponding monomer. <3> A large particle with a small charge will have great mobility. <4> A small particle of great load will have great mobility. <5> A charged micelle will have less mobility than another micelle of the same size but neutral.
Solution:
4
