/**
 * ## Response Element Specifications
 *
 * The portion of a question that a student interacts with and that determines the "kind" of question
 * (e.g. multiple choice vs. fill-in-the-blank) is the "response element". The response element is
 * specified as a portion of the overall question specification. For example, here are two different
 * approaches to a question about tomatoes:
 *
 * **Question with a `"multiple_choice"` response:**
 * ```typescript
 * export const Question_Sample_MC : QuestionSpecification = {
 *   question_id: "sample_mc",
 *   points: 2,
 *   mk_description:
 * `
 * This is a sample question. Which of the following is NOT an heirloom variety of tomato plant?
 * `,
 *   // vvv RESPONSE ELEMENT SPECIFICATION vvv
 *   response: {
 *     kind: "multiple_choice",
 *     choices: ["Green Zebra","Better Boy","Black Krim","Mr. Stripey","Brandywine"],
 *     multiple: false,
 *     sample_solution: [1],
 *     default_grader: // NOT SHOWN
 *   }
 *   // ^^^ RESPONSE ELEMENT SPECIFICATION ^^^
 * }
 * ```
 *

 *
 * **Question with a `"fill-in-the-blank"` response:**
 * ```typescript
 * export const Question_Sample_MC : QuestionSpecification = {
 *   question_id: "sample_mc",
 *   points: 2,
 *   mk_description:
 * `
 * This is a sample question. Classify the following tomato varieties. Write either "heirloom" or "hybrid" in each box.
 * `,
 *   // vvv RESPONSE ELEMENT SPECIFICATION vvv
 *   response: {
 *     kind: "fill_in_the_blank",
 *     content:
 * `________BLANK________ Green Zebra
 *
 * ________BLANK________ Better Boy
 *
 * ________BLANK________ Black Krim
 *
 * ________BLANK________ Mr. Stripey
 *
 * ________BLANK________ Brandywine`,
 *     sample_solution: ["heirloom", "hybrid", "heirloom", "heirloom", "heirloom"],
 *     default_grader: // NOT SHOWN
 *   }
 *   // ^^^ RESPONSE ELEMENT SPECIFICATION ^^^
 * }
 * ```
 *

 *
 * A response element specification will always contain the `kind` property, which must be one of the
 * string literal types of [[`ResponseKind`]]. This acts as a discriminant for the overall type of the
 * response element specification by selecting for the corresponding type of response specification:
 *
 * - `"multiple_choice"`: [[`MCSpecification`]]
 * - `"fill_in_the_blank"`: [[`FITBSpecification`]]
 * - `"select_lines"`: [[`SLSpecification`]]
 * - `"code_editor"`: [[`CodeEditorSpecification`]]
 * - `"fitb_drop"`: [[`FITBDropSpecification`]]
 *
 * This means you'll get intellisense support (e.g. autocomplete suggestions) for the available options
 * you may specify given whatever you chose for the `kind` of the response element. It also means you'll
 * get compile errors if you specify something contradictory or if you leave out a required property.
 *
 * See the documentation for each response kind for more information about its configuration.
